Major version bump (postgres) — auto-merge is intentionally disabled for semver-major updates. Review the upstream changelog and merge manually.

Looks like postgres is no longer being updated by Dependabot, so this is no longer needed.

Closing this one: 18.6 is two PostgreSQL majors up from what the compose file runs, and a major changes the on-disk format, so it needs pg_upgrade or a dump and restore rather than a new image tag. Self-hosters pulling this would get a container that cannot read their data directory.

The ecosystem config now ignores major updates for this image, so minor releases keep arriving here and a major stays a deliberate decision with a migration path behind it.
