Hmm ... we do use that syntax in some fairly-obscure places like
ALTER OPERATOR, but I'm afraid that novice users would just be
completely befuddled. Maybe the examples would be enough to clarify,
but I'm not convinced. Especially not for unary operators, where
ALTER OPERATOR would have us write "- (NONE, integer)".
