Perhaps it would be easier to allow SKIP VALIDATION (or something) with
ALTER TABLE ADD .... which can set FkConstraint->skip_validation. If we're
just handling pg_dump output, then presumably the data is already
validated. On the other handle, it might encourage users to bypass FKs
when they feel like it...
