Something really amazing in PostgreSQL is the HINTs system in error
messages. Almost all the time thoses messages are focused and helping.
I'd see this warning as a HINT maybe: WARNING: variadic function xxx(int, int[]) already exists HINT: you would rather
notto mask it 

Well, I'm not sure WARNING HINTS are supported, it's more a way to
better explain the idea  than anything else.

The bottom line was that I'm betting DBA would be happy to know and
wouldn't consider it annoying noise, and for the kind of "Please, I
know what I'm doing" DBAs, maybe some kind of warning_level GUC would
be desirable?

I'd still vote in favor of the NOTICE/WARNING. I know I'd be happy to
have my beloved PostgreSQL being attentive and focused when maybe I'm
not. Even if this time I was.
