I think if we really wanted to design this generally, we'd give a type
function arguments.  So, numeric would get (int default = 0, int default
= 0).  That can easily get very complicated, of course.

In any case, for the shorter term, it's clear that refactoring the
passing around of type + typmod would help this endeavor, so I'm going
to give it a try.
