# database that already has some of them applied will fail on the
# first one that already exists (e.g. "relation already exists") — a
# real migration tool (golang-migrate, etc.) would be the right call
# the moment this needs to run against a partially-migrated database
# rather than only a fresh one.

# "default" instead of erroring.

# real databases, not mocks. -p 1 forces packages to run one at a
# time: internal/store and internal/analytics both mutate the same
# live, shared Postgres tables, and Go runs different packages'
# tests concurrently by default, which caused exactly the kind of
# flaky cross-package interference this is here to prevent.
