What I did
PostgreSQL 18.3 was released February 26th, and I consider 18 to be stable now.
This will prompt users to migrate to 18.
PostgreSQL has changed where it expects data. The cleanest way I found to handle this is to set
PGDATAmanuallyand mount the volume outside of
/var/lib/postgresql, to avoid issues that arise from conflicts between old and new.Old: Mount to
/var/lib/postgresql/dataNew: Mount to
/var/lib/postgresql,datais a symlink, DB is in<MAJOR_VERSION>/dockerI set
PGDATA=/var/lib/postgres-dataand mount the volume to there. That allows existing users to work and have slashing protection, it allows new setups, and it allows migration.Also strengthened error handling.
Pucker factor is high: A fatal bug here gets people slashed.
This is the third migration since the code was introduced. First was 15->16, second 16->17, now 17->18.
