Actually, I wish this was a straight-up logging level feature, because I 
need it all the time when debugging complicated user-level code. 
Specifically, I wish there was a GUC that would alter 
(client|log)_min_messages upon entering a specific function, either for 
just that function or for anything that function subsequently called. 
Bonus points if you could also specify a regex that the message text had 
to match.

I realize that code-wise that's completely incompatible with what you're 
discussing here, but I think the same API could be used (maybe as a 
different GUC).
