There are paths that can reach that notice --- I think what you have to
do is create a new function that references a built-in one.  But why
we bother to warn for that isn't clear to me.

I think this is a hangover from the fact that CREATE FUNCTION's LANGUAGE
clause used to insist on the language name being a string literal, and
of course the lexer didn't case-fold it then.  That's been deprecated
for long enough that we probably don't need to have the extra case-fold
step anymore.
