I'd like to avoid exposing PostgreSQL via TCP when application and database run on the same system - This can be done by connecting over a UNIX domain socket connection. (This also allows PostgreSQL to use "peer" authentication, avoiding the PostgreSQL password altogether)

Drizzle URLs cannot encode PostgreSQL UNIX socket connections (https://github.com/drizzle-team/drizzle-orm/issues/4867), although the underlying library supports them. It would be nice to support UNIX connections in some way (maybe via a DATABASE_SOCKET environment variable as an alternative to DATABASE_URL).
