Fix mistake in bbe08b8.

The earlier commit used pg_class.relfilenode where it should have used pg_class.oid. This could lead to emitting an UPDATE statement into the dump that would update nothing (or the wrong thing) when executed in the new cluster, resulting in relfrozenxid and relminmxid being improperly carried forward for pg_largeobject. Noticed by Dilip Kumar. Discussion: http://postgr.es/m/CAFiTN-ty1Gzs6stk2vt9BJiq0m0hzf=aPnh3a-4Z3Tk5GzoENw@mail.gmail.com
