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.
