Postgres Job Queues and Failure by MVCC | Hacker News
If you're using an external queue such as RabbitMQ, there's basically no way to guarantee a queue message being fired without a "two-phase" transactional approach.

Let's say your use case is creating a user and sending an email verification email. You need to:

1. Start transaction.

2. Create the user.

3. Insert a tuple into an "events to fire" table.

4. Commit.

5. Fire the event.

6. Delete the tuple.

This ensures that if the transaction fails, nothing is fired; if the transaction succeeds, we guarantee that the user now exists, and that the command to fire the event also exists. Thus, if step 5 fails, we still have the "events to fire" tuple, and we can have a cron job running every minute that picks up stragglers. (In practice, you'll need to run steps 5-6 in a transaction that exclusively locks the tuple so that a concurrent cron job doesn't do it.)
