Yep. I expressed my own doubts in the post I suggested that in.

If Pg did auto-correct down, it'd be necessary to scream about it
angrily and continuously, not just once during startup. Given that it's
clear many people never even look at the logs ("what logs? where are
they?") I think Pg would also have to send notices to the client.
Problem is, many clients don't process notices/warnings, so particularly
slack admins won't see that either.

I'm not particularly excited about the idea.
