Yeah, I think it's fine if parent gets dumped without one or more of
its children, that's user's choice when it used a certain pattern.
Problematic case might be when we dump a child without its parent and
have INHERITS clause there. pg_restore would throw an error. But in
case that problem exists it's very old and should be fixed separately.
