One of the biggest benefits imo of using Postgres as your application queue, is that any async work you schedule benefits from transactionality.

That is, say you have a relatively complex backend mutation that needs to schedule some async work (eg sending an email after signup). With a Postgres queue, if you insert the job to send the email and then in a later part of the transaction, something fails and the transaction rollbacks, the email is never queued to be sent.

Good point. We alleviate that a bit by scheduling our queue adds to not run until after commit. But then we still have some unsafety, and if connection to rabbit is down we're in trouble.
