It's a fair question.
I can imagine designing things so that we don't create an explicit
pg_constraint row for the simplest case of an unnamed, non-inherited
NOT NULL constraint. Seems like it would complicate matters quite
a lot though, in exchange for saving what in the end isn't an enormous
amount of space.
