Yeah. If we're going to allow this then we should just have a concept
of a non-inherited constraint, full stop. This might just be a matter
of removing the error thrown in ATAddCheckConstraint, but I'd be worried
about whether pg_dump will handle the case correctly, what happens when
a new child is added later, etc etc.
