So AIUI your suggestion is that ALTER/DROP ROUTINE will look for an
ambiguity. If it doesn't find one it proceeds, otherwise it complains in
which case the user will have to fall back to ALTER/DROP
FUNCTION/PROCEDURE. Is that right? It seems a reasonable approach, and I
wouldn't expect to find too many ambiguous cases in practice.
