New Postgres databases created from the template use the official Postgres 16 image with **pgvector** included. Run `CREATE EXTENSION vector;` to store embeddings, and apps that need it, such as Chatwoot 4, migrate without extra steps. Existing databases keep their image.

#### Postgres 18 on the usual mount

Postgres 18 images refuse a volume mounted at `/var/lib/postgresql/data` unless `PGDATA` is set. When you deploy a Postgres 18 or newer image with its volume at that path and no `PGDATA` of your own, Unbroker sets it for you. Versions 17 and older are never changed.

#### PostGIS, TimescaleDB and pgvector images

Services that run `postgis/postgis`, `timescale/timescaledb` or `pgvector/pgvector` are recognized as Postgres. They get the database tunnel, the data browser, `pg_dump` backups and database resource defaults. A volume created before this keeps the owner it already had, so redeploying it is safe.
