Sounds handy.

My "|" is simply a syntactic shorthand for a special case of CREATE SYNONYM, with respect to schema objects, and would parse into the same thing. I don't feel any need now for me to push this shorthand further. -- Darren Duncan

I can't get excited about it. I'm just happy the functionality is there. I was able to both simplify my PL/pgSQL code *and* make it much clearer what it's doing:

http://github.com/theory/pgxn-manager/commit/e136ccb342010e836c39dafa43b802478be445a0

That said, I'm assuming that the function-name block is really a RECORD object representing the argument signature. I could see a case for PL/pgSQL just having an "ARGS" variable or something that does the same thing. Kind of like triggers have NEW and OLD. But given that the functionality is already there, that's just gravy. Or sugar. I'm not sure which. Sugary gravy.

Best,
