I maintain a small Postgres-native job queue for Python called PGQueuer: https://github.com/janbjorge/pgqueuer

It uses the same core primitives people are discussing here (FOR UPDATE SKIP LOCKED for claiming work; LISTEN/NOTIFY to wake workers), plus priorities, scheduled jobs, retries, heartbeats/visibility timeouts, and SQL-friendly observability. If you’re already on Postgres and want a pragmatic “just use Postgres” queue, it might be a useful reference / drop-in.
