Show HN: PgQueuer – A PostgreSQL job queue that works without PostgreSQL (github.com)

PgQueuer turns PostgreSQL into a background job queue using LISTEN/NOTIFY and FOR UPDATE SKIP LOCKED. v0.26.0 adds an in-memory adapter so you can run the same code in tests and CI without a database. Internally it's now built on port protocols, so you can swap the persistence layer entirely.
