Hmm, okay, but not-null constraints on domain cannot be NOT VALID at
present.  I think it would be a useful feature (so that users can make
domains not-null that are used in tables already populated with data),
but first you'd need to implement things so that each table has a
not-null constraint row for the column whose type is the domain that's
being marked not-null.

Anyway, here's a patch.
