No, I can't compile it. It just *looks* like the behaviour was broken
by that commit. Sorry for the confusion.

Please correct me if I'm wrong, but as far as I can tell we can't do
that check at compile time because we don't do parse analysis. And
making that happen every time CREATE FUNCTION is called.. I don't see
that happening.
But making this check at run time doesn't seem too hard. How broken
does the attached look? It passes all the existing regression tests, at
least..
