I don't see where "call a setup function immediately after connecting"
Sounds like a "login trigger", more generally an ON CONNECT
event trigger, which we don't have at the moment as far as I
know.
One of the main arguments against it was that a failing
trigger function might prevent all access while the suggested
solution to that (I think by Tom Lane) was to auto-disable ON
CONNECT triggers when starting up as --single.
I'll take some credit for a partial solution suggestion:

and pass most of the credit back to you for a better one:

While the notion of an ON CONNECT trigger seems interesting, the rest of that discussion thread had
a lot of good points about challenges to successfully implementing this idea.
