Hi Tom.
Indeed it was. I shared my psql session showing that.

That's better than nothing. And I get it's likely complex.
But still, arg names are not part of the signature.
So they should be checked after the fact.
In my case, the SCHEMA eas explicit, so no search_path.
With the ::name cast, the signature was an exact match.
And there are no overloads at all.
So it's possibly the "worse case" for saying the proc does NOT exist...
It's like the code should do a LEFT JOIN instead of a JOIN on arg names :).
