Queue Implementation for/with PostgreSQL - Mailing list pgsql-general

Hi,

Does Postgres support queues, I mean does it have something like
Oracle's Advanced Queue. If not, can you please recommend an
open-source, light-weight and more importantly RELIABLE point-to-point
queue implementation, built on postgres? Something similar to Oracle's
Advanced Queue? I don't need publish/subscribe or a priority-based
point-to-point queue, just a simple one which provides a reliable way
of enqueuing and dequeuing with LIFO...

Thanks...
