So you are willing to prohibit a(int) from existing in parallel with
a(int, int-with-a-default) ?
I'll be interested to see the unique-index scheme for pg_proc to enforce
that ;-)
However this does point up the fact that there already *is* a way to
accomplish the task, which is just to create some helper function(s) to
supply the default(s). Perhaps we can leave it at that for the time
being, and concentrate on adding real new functionality.
