In fact it won't, because the spec's rule is simply "you can't have
two procedures with the same name and same number of parameters"
(where they count OUT parameters, I believe).  However the case
I was considering was wanting to have

	create procedure divide(x int, y int, OUT q int) ...
	create procedure divide(x numeric, y numeric, OUT q numeric) ...

which likewise falls foul of the spec's restriction, but which
IMO must be allowed in Postgres.
