Release notes

Sourced from github.com/jackc/pgx/v5's releases.

v5.11.0

This release adds direct PostgreSQL type scanning through database/sql on Go 1.27, improves compatibility with libpq connection strings and PostgreSQL date/time values, and includes further decoder hardening. See Changes for connection-string and date/time behavior changes that may affect existing applications.

Features

• stdlib: support Go 1.27's driver.RowsColumnScanner, allowing PostgreSQL types such as arrays and ranges to be scanned directly into Go values without pgtype.Map.SQLScanner. Existing database/sql scalar conversions and sql.Scanner behavior are preserved. The minimum supported Go version remains 1.25.
• Add Rows.TypeMap to expose the type map used to decode rows, including rows created by RowsFromResultReader that have no underlying Conn. Custom implementations of Rows, including mocks, must add this method.
• pgconn: add Config.MaxProtocolMessageBodyLen to configure the maximum incoming protocol message body size (carter-ya)
• pgconn: add ErrReadOnlyConnection, ErrReadWriteConnection, ErrPrimaryConnection, and ErrStandbyConnection sentinel errors for target_session_attrs validation, allowing callers to use errors.Is (Adrian-Stefan Mares)
• pgxpool: accept pool_ping_timeout in connection strings to configure Config.PingTimeout. The default is zero; zero and negative durations mean no timeout (1991santhu)

Changes

• Name-based row-to-struct mapping now matches explicit db tags case-insensitively, with exact matches taking precedence so tags can still distinguish quoted column names that differ only by case (AlisinaDevelo)

• pgconn: resolve the OS user account only when no user is supplied by the connection string, environment, or service file, avoiding unnecessary account lookups and crashes in some restricted container environments. Home-directory defaults for password, service, and TLS files remain available independently of the account lookup. On Unix these now use $HOME rather than the OS account's home directory (Mohamed MAACHE)

• pgtype: date, timestamp and timestamptz text values are now parsed and written by a hand-written parser and encoder for PostgreSQL's ISO date/time format instead of time.Parse and time.Format. Go's layout language cannot express a variable-width year or the BC era, which is the root of the bugs below. The text scan path is roughly 2.5x faster for timestamp and timestamptz. Bug fixes:

  • timestamp and timestamptz no longer silently move February 29 of a BC leap year to March 1 when encoding. time.Date(-4712, 2, 29, ...) was written as 4713-03-01 BC and is now written as 4713-02-29 BC. This affected ordinary four-digit BC years, not only extended-range ones. date was never affected.
  • timestamp and timestamptz can now scan BC leap days. 4713-02-29 BC previously failed with day out of range. date could already scan them.
  • Years past 9999 can now be scanned. 10000-01-02 03:04:05 previously failed to parse, so timestamp and timestamptz values at the high end of PostgreSQL's range were unreadable over the simple protocol and in any other text-format result.
  • time.Time arguments in the simple protocol now encode BC dates correctly, using the same timestamp encoder.
  • Fractional seconds beyond microsecond precision are rounded the way the server rounds them (round half to even, carrying into the rest of the value) instead of being kept at full precision. PostgreSQL never sends more than six fractional digits, so this only affects values from other sources.

  Behavior changes:

  • date now rejects impossible dates instead of normalizing them. 2024-02-30 returned 2024-03-01 and 2024-13-01 returned 2025-01-01; both are now errors. timestamp and timestamptz already rejected them.
  • All three types now reject values outside PostgreSQL's range for that type, in the binary format as well as the text format. PostgreSQL never sends out-of-range dates, so this only affects corrupt or hand-built input; the range

Changelog

Entries for v1.38.1 through v1.44.1 and for v1.49.1 were added on 2026-09-05, reconstructed from the git history and the merge requests they cite; they were missing at release time.

• 2026-09-05 v1.59.0:

  • Hand user-defined function and aggregate callbacks a pooled *FunctionContext instead of allocating a fresh one per call. After the []driver.Value pooling of #226 this was the last driver-side heap allocation per invocation: one 16-byte object for every Scalar, Step, WindowInverse, WindowValue and Final call. The context now also carries the invocation's sqlite3_context, so accessor methods can be added to it later without touching the trampolines. Like the argument slice, it is valid only for the duration of the callback and must not be retained past its return; the documentation on FunctionContext and on the callbacks now says so. On the 1000-row, 3-argument noop scalar UDF benchmark this removes a further 1000 allocs/op (5756 to 4756, and 3756 to 2756 with VolatileArgs) and 16 KB/op; on the reporter's reproducer from #226 it removes about 12% of the remaining allocations (25.3M to 22.4M allocs/op, 553 MB to 505 MB per iteration).
  • Updates [GitLab issue #226](https://gitlab.com/cznic/sqlite/-/issues/226). See [GitLab merge request #137](https://gitlab.com/cznic/sqlite/-/merge_requests/137).
  • Add regression tests for the pooled context: two functions evaluated in one statement must receive two different sqlite3_context values and every callback's context must belong to the invoking connection, checked on two connections held at once and without dereferencing the context, so that a stale one is reported rather than faulted on; eight connections held at once calling a function from their own goroutines, and a function that runs a statement invoking another function, both meant for the race detector. See [GitLab merge request #138](https://gitlab.com/cznic/sqlite/-/merge_requests/138), thanks Ian Chechin!

• 2026-09-01 v1.58.0:

  • Upgrade to SQLite 3.53.4. Upstream's own fix for the journal-rollback data-corruption bug is part of this release, so the local super-journal patch v1.56.0 introduced — and promised to drop once upstream shipped theirs — is dropped; recovery behavior is unchanged. This also bumps the pinned modernc.org/libc to v1.75.6; as always, downstream modules must pin the exact modernc.org/libc version this module's go.mod pins (see [GitLab issue #177](https://gitlab.com/cznic/sqlite/-/issues/177)).
  • Add opt-in support for Linux Open File Description (OFD) locks on database files. A POSIX record lock is owned by the (process, inode) pair, so the kernel drops every lock the process holds on a database file whenever any descriptor of that file is closed: an os.Open/Close for a hash, a backup check or a metadata probe anywhere in the process — third-party libraries included — silently strips SQLite's transaction locks and leaves the file unprotected against other processes. With OFD locking enabled, the locks belong to the open file description that placed them and survive such a close. Off by default, and staying off until the mode has real-world mileage: without opting in, locking behavior is byte-for-byte that of previous releases. Enable it by setting MODERNC_SQLITE_OFD_LOCK=1 in the environment the process starts with (any value but the empty string or one starting with 0; read once, at library initialization), or from Go with the new OFDLocking(true), which overrides the variable and must run before the first connection is opened; OFDLockingEnabled reports the mode in effect. The switch is deliberately process-wide rather than a DSN parameter: POSIX and OFD locks taken by one process are different owners to the kernel and genuinely conflict, so every connection to a database file inside one process must use the same kind, and a per-DSN knob would advertise a granularity the kernel does not offer (see the discussion in #255). Because the two kinds do not release one another, the mode is frozen at the process's first lock attempt: later attempts to change it return the new ErrOFDLockingTooLate, while querying, and setting the value already in effect, keep working. On kernels older than 3.15, and on filesystems that reject OFD locks, the first lock attempt falls back to POSIX locks for good and OFDLocking returns the new ErrOFDLockingUnavailable from then on, which is also how OFDLockingEnabled turning false reports the fallback; the same error is returned on every platform but Linux, where the API exists but OFD locks do not. Two boundaries to note: the immunity covers the locks on the database file itself, while WAL's -shm coordination stays on POSIX locks; and code in the same process that takes fcntl record locks of its own on a database file — which used to never conflict with SQLite's, while quietly destroying them — now conflicts with them loudly instead. The C side — F_OFD_SETLK routing through a designated per-inode locking descriptor that preserves upstream's unixInodeInfo semantics (last-unlocker release, PENDING piggybacking, unix-excl), guarded to __linux__ — ships in the transpiled sources via libsqlite3!3 and its follow-up hardening, with the OFD lock constants from libc!33; the review rounds, the /proc/locks measurements behind the design, and the Tcl lock/WAL gate that runs both modes are recorded in [GitLab issue #255](https://gitlab.com/cznic/sqlite/-/issues/255) and those merge requests.
  • Add the accompanying regression tests. The four OFD scenarios contributed in merge request #136 — lock survival across a rogue os.Close, the interleaved-readers lock lifecycle, the read-only-first designated-descriptor migration, and the failed-first-lock cleanup — run in a re-executed child process with MODERNC_SQLITE_OFD_LOCK=1, since the mode is process-wide and frozen at the first lock so the suite's own process cannot switch; a positive control asserts the variable really switched the mode on before each scenario runs, and the two scenarios whose invariants hold under both modes also run in the parent process's inherited mode. TestOFDLockingSetter exercises the Go call path end to end in a clean child — off by default, enabled before the first connection, the kernel-visible OFDLCK record in /proc/locks as the positive control, frozen after the first lock — and on every other platform the switch is asserted to report itself unavailable.
  • Resolves [GitLab issue #255](https://gitlab.com/cznic/sqlite/-/issues/255). See [GitLab merge request #136](https://gitlab.com/cznic/sqlite/-/merge_requests/136), thanks Nathan Herring (@​technosloth), and thanks Gani Georgiev (@​ganigeorgiev) for pressing the opt-in default!

• 2026-08-19 v1.57.0:

  • Add an opt-in _defensive DSN query parameter that turns on SQLite's defensive mode for the connection, disabling the SQL-level features that let ordinary statements deliberately corrupt the database file. When _defensive=1 (or any strconv.ParseBool true value) is supplied, the driver calls sqlite3_db_config with SQLITE_DBCONFIG_DEFENSIVE immediately after sqlite3_open_v2 and before every other parameter is applied, so the PRAGMAs the driver itself runs, the _pragma list, and every statement the caller prepares are all subject to it. On such a connection PRAGMA writable_schema=ON, PRAGMA journal_mode=OFF and PRAGMA schema_version=N become silent no-ops, and writes to a virtual table's shadow tables (fts5's _data, _idx and so on) and to sqlite_dbpage fail with "table ... may not be modified"; reading those tables, ordinary use of the virtual tables that own them, and VACUUM are unaffected. The flag has no PRAGMA equivalent, so sqlite3_db_config — and therefore a DSN parameter — is the only way to reach it short of dropping to modernc.org/sqlite/lib. The value is parsed before sqlite3_open_v2, so an invalid one fails the connection without creating the database file, and the parameter must appear at most once: a repeated _defensive is an error rather than letting the first value silently win. Absence of the parameter, or _defensive=0, leaves SQLite's default behavior unchanged; existing DSNs continue to work byte-for-byte. Two limits are worth stating plainly, since the name invites more confidence than the flag earns. Defensive mode is a hardening measure, not a sandbox for hostile database files: it is one of several steps SQLite recommends for that purpose, and this build compiles with neither SQLITE_TRUSTED_SCHEMA=0 nor SQLITE_DQS=0 and exposes no authorizer. And it is a property of the connection, not of the database file — a second handle opened on the same file without the parameter is unrestricted.
  • Reject the one DSN combination defensive mode would otherwise swallow in silence. _defensive=1 together with _journal_mode=OFF (or _journal=OFF) now fails the connection instead of opening one in which neither parameter was honoured: SQLite turns PRAGMA journal_mode=OFF into a no-op that still reports success, so the driver would have accepted the mode, executed it, and left the journal untouched without telling anyone. The check runs in the validation phase introduced in v1.55.0, before any statement executes, so a rejected DSN cannot leave the database half-configured. _pragma remains the exception it has always been: _pragma=journal_mode(OFF) alongside _defensive=1 still runs and is still silently ignored by SQLite. Only DSNs using _defensive can be affected, and that parameter is new, so no DSN that opened before changes behavior.
  • See [GitHub pull request #6](modernc-org/sqlite#6), thanks wsman!
  • Ship the sqlite-vec license notice this module has been missing. modernc.org/sqlite/vec has bundled the transpiled sqlite-vec sources since v1.47.0, but the module carried only its own BSD-3-Clause LICENSE and the public-domain SQLite notice. sqlite-vec is Copyright (c) 2024 Alex Garcia, dual-licensed Apache-2.0 OR MIT and used here under MIT, whose terms require the copyright and permission notice to accompany substantial portions of the software — which 2.8 MB of transpiled vec/ plainly is. The notice now ships as LICENSE-SQLITE_VEC in the module root, byte-identical to the LICENSE-MIT in the upstream v0.1.9 archive and named after the file modernc.org/libsqlite_vec extracts it into. Attribution was never absent — vec's package documentation has named the extension, pinned the version and linked upstream — but the license text itself was, and the omission was ours: vendor_libs/main.go copied the per-target transpiles and nothing else. It now copies the notice alongside them and fails the vendoring run if it cannot, so a make vendor can no longer quietly drop it. The vec package documentation gained a License section recording that the package is under a different license from the rest of this module.
  • The SQLite notice is renamed from SQLITE-LICENSE to LICENSE-SQLITE; update any direct links to it. Its contents are unchanged and SQLite remains public domain. The name now matches both the new LICENSE-SQLITE_VEC beside it and the LICENSE-<upstream> convention every other modernc.org repository follows, but it is more than cosmetic: go mod vendor selects the files it copies into a downstream vendor/ tree by matching each name against a fixed list of prefixes — LICENSE among them — so a name merely ending in LICENSE was never propagated. Both bundled notices now travel with the code into vendored builds, which is where the MIT terms on vec/ keep applying. No code changes; no behavior changes.
  • Let a caller-constructed Driver register its own functions, collations and virtual table modules. Driver has always held four categories of registration state, but only RegisterConnectionHook could put anything on a constructed one: functions and collations were reachable through the package-level API alone, and modules through the package-level driver only, which left the modules field written and read through that instance and so process-global state wearing a per-instance field. Driver now has RegisterFunction, RegisterScalarFunction, RegisterDeterministicScalarFunction, RegisterCollationUtf8 and RegisterModule, plus Must* variants of the first four, each registering on that Driver alone; the methods are safe to call concurrently, and the zero Driver is ready to use as-is. vtab.RegisterModule also honours its db argument now: a non-nil db registers on the driver backing it when that driver implements the new vtab.ModuleRegisterer, while a nil db keeps targeting the driver this package registers as sqlite. One existing pattern changes behavior, narrowly and loudly: vtab.RegisterModule(db, ...) where db was opened on a caller-constructed Driver used to discard the db argument and land on the sqlite driver, reaching every connection in the process; it now lands on the constructed driver alone, so a sql.Open("sqlite") connection that used to resolve such a module gets no such module instead. The same pattern is also the one way an existing program could hold one module name on both a constructed Driver and the package-level one: there the first of the two registrations used to win and the second was refused as already registered, whereas now the package-level implementation wins on the constructed Driver's connections regardless of the order they ran in. Reaching that case at all means the program ignored an error the older version returned. Two smaller deviations round out the list: Driver.RegisterModule reports no error for such a collision, and vtab.RegisterModule now validates its name and module arguments before the not-implemented check, so a call with an empty name that returned vtab: RegisterModule not wired into engine outside this driver returns vtab: module name must be non-empty instead. Everything else is additive against v1.56.0: the package-level registration functions target the same driver they always did, connections still receive every module registered through the package-level path whichever Driver opened them, and a db opened on the sqlite driver resolves to that same driver. The isolating change discussed in [GitLab issue #254](https://gitlab.com/cznic/sqlite/-/issues/254) is deliberately not made here.

  • Promote freebsd/386, freebsd/arm and netbsd/amd64 to fully supported platforms. All three are now listed in the package documentation's platform table, which had carried seventeen entries while this module shipped, cross-built and tested twenty. They arrived as experimental in v1.53.0 — netbsd/amd64 reviving a port that had been broken for years, freebsd/386 replacing a stale, effectively untested SQLite 3.41 transpile, and freebsd/arm entirely new — and were deliberately kept out of that table until they had accumulated real-world exposure, with promotion promised once "a period of broader real-world testing … elapses without surprises". That period has elapsed: all three have been in the builder test matrix and in make build_all_targets since v1.53.0, all three pass the full test suite on this release's commit alongside the seventeen platforms already listed, and no open issue reports a defect in any of them. The two netbsd/amd64 build failures filed before the revival, [GitLab issue #202](https://gitlab.com/cznic/sqlite/-/issues/202) and [GitLab issue #234](https://gitlab.com/cznic/sqlite/-/issues/234), no longer reproduce at this commit: Xsqlite3_is_interrupted is present in the sources that target selects, and the mu.enter/mu.leave symbols that broke the build are gone. Documentation only — the transpiled sources under lib/ are byte-for-byte what v1.56.0 shipped, and nothing about how these targets behave changes.

• 2026-08-03 v1.56.0:

  • Re-vendor the transpiled SQLite sources, picking up modernc.org/libsqlite3's fix for an upstream data-corruption bug in SQLite 3.53.3's journal rollback. The SQLite version is unchanged at 3.53.3; what changes is that the amalgamation is now patched before it is transpiled. 3.53.3 reworked readSuperJournal() to return the super-journal name through a char** out-parameter, and pager_playback() now tests that pointer where it used to test zSuper[0]. A crash during the commit of a multi-database (ATTACH) transaction can leave the super-journal name and its checksum zeroed while the name length and the trailing magic survive; the checksum is a plain byte sum, so an all-zero name still validates and readSuperJournal() hands back a non-NULL pointer to an empty string. pager_playback() then calls sqlite3OsAccess(pVfs, "", SQLITE_ACCESS_EXISTS), gets ENOENT, and deletes the hot journal without playing it back — leaving the database corrupted. This is not a transpilation artifact: a plain gcc build of the stock 3.53.3 amalgamation fails on the same bytes while 3.53.2 recovers them, and it is what has been making upstream's own test/crash.test fail intermittently, in roughly 2% of runs, on every platform. The patch restores the pre-3.53.3 behaviour of reporting a (nul) super-journal name and will be dropped once upstream ships its own fix. Every supported target carries it.
  • Two targets change beyond that patch. On linux/s390x the regenerated transpile allocates C bit-fields MSB-first, as the big-endian platform ABI requires, rather than LSB-first; this comes from modernc.org/cc/v4 v4.29.1 and touches bit-field accesses throughout the SQLite core, s390x being this module's only big-endian target. On linux/riscv64 the transpile was regenerated on a host running GCC 11.4.0 where the previous one used GCC 13.3.0, which drops a handful of unexported compiler-predefined macro constants (the __FLT16_* family, __DBL_IS_IEC_60559__ and friends) and changes the COMPILER=gcc-13.3.0 entry PRAGMA compile_options reports to COMPILER=gcc-11.4.0; no SQLite code generation differs. Every other target's generated code is byte-identical to v1.55.0 apart from the journal-rollback patch above.
  • Bump the pinned modernc.org/libc to v1.74.4, and the remaining dependencies to their current releases. v1.74.2 and v1.74.3 are retracted upstream — a freeaddrinfo lock leak that deadlocks name resolution — and v1.74.4 is the fix. As always, downstream modules must pin the exact modernc.org/libc version this module's go.mod pins (see [GitLab issue #177](https://gitlab.com/cznic/sqlite/-/issues/177)).
  • Documentation sweep. openbsd/amd64 and openbsd/arm64 join the supported platforms table in the package documentation: both have been in the builder test matrix since January and are cross-built by make build_all_targets, but had never been listed. The vfs DSN query parameter — which names a VFS registered with SQLite, such as one returned by vfs.New — is now documented alongside the other DSN parameters on Driver.Open. The "Debug and development versions" section no longer describes a GO_GENERATE environment variable and a go generate that this repository has not had since generator.go moved to modernc.org/libsqlite3; it now points at that repository and make vendor instead, and the stale //go:generate directive naming the removed file is dropped with it. modernc.org/sqlite/vec and modernc.org/sqlite/vfs gained the package doc comments they were missing, so both finally carry a synopsis on pkg.go.dev. Documentation only; no behavior changes.
  • Add NewConnector, returning a database/sql/driver.Connector for use with sql.OpenDB. It opens the same connections sql.Open("sqlite", dsn) does, from the same registered driver, so every function, collation, connection hook and virtual table module registered through this package applies to them. It exists for callers that need to interpose on the physical connections database/sql opens — tracing, metrics, connection-scoped setup — which sql.Open gives no access to: such a caller can embed the returned Connector, override Connect, and pass its own wrapper to sql.OpenDB. Previously the only way to reach the registered driver was the db, _ := sql.Open("sqlite", ""); drv := db.Driver(); db.Close() idiom, which works only because sql.Open does not connect and this driver does not implement driver.DriverContext; and the only way to get a wrapper into a *sql.DB was sql.Register, which is process-global, panics on a name it has already seen, and cannot be undone, so a library had to invent a unique driver name per configuration. sql.OpenDB registers nothing. Constructing a &sqlite.Driver{} is not an alternative — its fields are unexported, so it carries none of the registrations. NewConnector checks the DSN only as far as it can without opening a database — a query string that does not parse, and conflicting vfs parameters; everything else continues to be validated when the connection is opened, so an unknown parameter or an out-of-range value is reported by Connect rather than at construction. Nothing about the existing sql.Open path changes: *Driver deliberately still does not implement driver.DriverContext, so sql.Open remains lazy and DSN errors continue to surface where they always have. A runnable sample is in examples/connector. Resolves [GitLab issue #253](https://gitlab.com/cznic/sqlite/-/issues/253), thanks Alessandro Segala (@​ItalyPaleAle)!
  • Document that a caller-constructed sqlite.Driver is not the driver this package registers as "sqlite". Its fields are unexported, so it starts with no functions, collations or connection hooks and the only way to give it any is its own RegisterConnectionHook method; the package-level Register* functions always apply to the registered driver. Connections such a Driver opens therefore run without the package-level functions and collations — and because a registered function silently replaces a SQLite built-in of the same name, a Driver you construct can evaluate upper(x), date(x) and the like differently from one opened through sql.Open. Virtual table modules are the one exception: they are held process-globally and reach every Driver. Constructing one remains supported for the private-hook pattern — a driver registered under a name of its own with sql.Register so its connection hooks apply only to its own connections — and is otherwise best avoided in favour of sql.Open or NewConnector. Documentation only; no behavior changes.

• 2026-07-20 v1.55.0:

  • Add github.com/mattn/go-sqlite3-compatible shorthand DSN query parameters to ease migration from that driver: _busy_timeout/_timeout, _foreign_keys/_fk, _journal_mode/_journal, _synchronous/_sync, _auto_vacuum/_vacuum, and _query_only, each setting the correspondingly named PRAGMA. Values are validated against the same set mattn/go-sqlite3 accepts (case-insensitive) and an unrecognized value fails the connection with an error, so a typo such as _synchronous=fu1l or _foreign_keys=yes_please is reported rather than silently downgrading durability or dropping foreign-key enforcement. The keys are applied in a fixed order independent of their order in the DSN — _busy_timeout and _auto_vacuum before any _pragma values (auto_vacuum must be set before the database is first written), the rest after, and _query_only last — and where a key and its alias are both supplied the alias wins, matching mattn/go-sqlite3; selection is by presence rather than by value, so supplying the alias empty (_foreign_keys=on&_fk=) suppresses the PRAGMA rather than deferring to the primary key, again matching that driver. Behavior change to note: prior releases ignored these keys entirely, so a DSN carried over from a mattn/go-sqlite3 setup changes in two ways. A recognized key that previously did nothing now takes effect — _foreign_keys=on begins enforcing constraints against data that may already violate them, _journal_mode=wal persistently converts the database file, and _query_only=1 makes the connection read-only. And a value outside the accepted set now fails the connection with an error where the same DSN previously opened successfully — for example a duration-style _busy_timeout=5s or _timeout=5000ms, neither of which is the integer that key requires. Review such DSNs before upgrading. _pragma is unchanged and no pre-existing parameter changes meaning, though see the following entry for a change in when all of them are validated.

  • Validate every DSN query parameter before applying any of them. Parameters were previously checked as each was reached, so a DSN whose later parameter was rejected had already executed the PRAGMAs ahead of it. Because PRAGMA journal_mode and PRAGMA auto_vacuum are persistent changes to the database file, a DSN such as file:x.db?_journal_mode=wal&_synchronous=bogus failed the connection and yet left x.db converted to WAL. A failed Open now leaves the database as it found it. This covers the pre-existing _txlock, _timezone, _time_format, _time_integer_format, _inttotime and _texttotime parameters as well as the shorthand keys above: all of them were validated only after the _pragma list had already run, so the same DSN shape — a valid _pragma=journal_mode=wal alongside a misspelled _txlock — converted the file before reporting the error. Only the values accepted for each parameter are unchanged; a DSN that opened successfully before still opens, and one that failed still fails with the same error. _pragma remains the sole exception, since its values are executed verbatim and cannot be checked in advance: a malformed _pragma is still rejected by SQLite as it runs, after any earlier _pragma in the list has taken effect.

• 2026-07-15 v1.54.0:

  • Upgrade to SQLite 3.53.3. This also bumps the pinned modernc.org/libc to v1.74.1; as always, downstream modules must pin the exact same modernc.org/libc version this module's go.mod pins (see [GitLab issue #177](https://gitlab.com/cznic/sqlite/-/issues/177)).
  • Under the opt-in _texttotime DSN parameter, best-effort parse date-shaped TEXT values from columns SQLite reports with an empty declared type — aggregates and expressions over a date column (MAX(d), COALESCE(d, ...), upper(d), d || ''), subqueries, and typeless real columns (CREATE TABLE t(x)) — into time.Time, instead of delivering them as a raw string that Scan cannot store into a *time.Time. The existing declared DATE/DATETIME/TIME/TIMESTAMP path is unchanged; this only adds the empty-decltype case. The conversion is strictly best-effort: a value that does not parse as a time falls through to the original string, so no Scan that worked before can newly fail. ColumnTypeScanType continues to report string for empty-decltype columns, since the declared type cannot prove the column is temporal. Without _texttotime the behavior is byte-for-byte unchanged. Resolves [GitLab issue #248](https://gitlab.com/cznic/sqlite/-/issues/248).

• 2026-06-21 v1.53.0:

  • Add experimental netbsd/amd64 support, resolving the long-standing build break in [GitLab issue #246](https://gitlab.com/cznic/sqlite/-/issues/246). This target is intentionally not yet listed among the supported platforms in the package documentation: the port had been broken for years and is only now revived, and there is as yet no real-world experience running it under production workloads. Green CI is not the same as battle-tested — so while the full test suite (including the pcache and vec packages and the -race concurrency test) passes on NetBSD 10.1 / Go 1.26.3, and the entire upstream toolchain (libc, cc, ccgo, libz, libtcl8.6, libsqlite3, libsqlite_vec) is green on the NetBSD CI builder, the target is offered for evaluation only. If you run NetBSD, please exercise it with your own workloads and report back via #246; the intent is to promote it to a fully supported platform after a period of broader real-world testing (on the order of a month) elapses without surprises.
  • Implementation notes: the previously shipped lib/sqlite_netbsd_amd64.go was a stale old-generator transpile that no longer compiled (the mu.enter/mu.leave break in #246); it is replaced by a fresh new-generator transpile consistent with every other platform, and modernc.org/sqlite/vec (sqlite-vec) is vendored and auto-registers on netbsd. Correct operation requires the matching pinned modernc.org/libc, which carries two NetBSD-specific fixes found during this work: the mmap(2) PAD-argument ABI (without it, concurrent WAL access faults with SIGBUS in the WAL-index shared memory) and a working abort(3) (the prior stub left SQLite's crash-recovery writecrash test unable to terminate by signal). As usual, downstream modules must pin the exact modernc.org/libc version this module's go.mod pins.
  • See [GitLab merge request #82](https://gitlab.com/cznic/sqlite/-/merge_requests/82), thanks Leonardo Taccari (@​iamleot) and Thomas Klausner (@wiz)!
  • Add experimental freebsd/386 and freebsd/arm support. As with the netbsd/amd64 target above, these two 32-bit FreeBSD ports are intentionally not yet listed among the supported platforms in the package documentation: freebsd/386 previously shipped a stale, effectively untested SQLite 3.41 transpile, and freebsd/arm is entirely new, so neither has real-world production mileage yet. Both are now freshly transpiled at SQLite 3.53.2 consistent with every other platform, build cleanly, and pass the full test suite (core, WAL/concurrency, and the vec package) on the FreeBSD CI builders; they are offered for evaluation only. If you run 32-bit FreeBSD, please exercise these targets with your own workloads and report back — the intent is to promote freebsd/386, freebsd/arm, and netbsd/amd64 to fully supported platforms in a future release cycle, once a period of broader real-world testing elapses without surprises.
  • Implementation notes: correct operation on freebsd/arm requires the matching pinned modernc.org/libc (v1.73.4), which fixes the per-arch mmap(2) off_t encoding for 32-bit FreeBSD; without it the WAL shared-memory mapping faults with SIGBUS under concurrent access, the same class of bug found on the netbsd port. As usual, downstream modules must pin the exact modernc.org/libc version this module's go.mod pins.
