After 578b229718 / the removal of WITH OIDS support, older dump files containing SET default_with_oids = false; either report unnecessary errors (as the subsequent tables have no oids) or even fail to restore entirely (when using transaction mode). To avoid that, re-add the GUC, but don't allow setting it to true.
Per complaint from Tom Lane.
