It actually depends on the workload.

Sending webhooks, as an example, often has zero need to go back and update the database, but I've seen that exact example take down several different managed databases ( i.e., not just postgres ).



Yes that's true but in good implementations you will want to surface to the recipient via some dashboard if delivery consistently fails. So at some point a message on the exception queue will want to update the db.


Whilst true, it probably doesn't need ACID / strong consistency.

Don't get me wrong. Correctness is a great default, much easier to reason about.


You're right, I think we're in agreement.
