Ah, nice, thank-you! > Fortunately our job throughput is small enough to not hit any scaling issues with Postgres, so I stuck with that because of my confidence and experience w/Postgres over the years. I think we're in a pretty similar situation. For what it's worth, I think that a queue in PG can scale up about as well as Postgres can as long as you keep an eye on the whole system (watch out for long-lived transaction and the like).
