While I was out at dinner, the obvious solution presented itself: define
\ef with no argument as being the command that presents an empty CREATE
FUNCTION command template to fill in. This isn't any more or less
typing than where I think you were going, and it eliminates all the
ambiguity about whether you meant to type a nonexistent function name
or just mistyped.
