I don't think it's a version issue; pg_class has always been OID 1259
(and relfilenode 1259, too). You might have version issues once you
started looking inside pg_class, but not before that.
Remember this is the guy whose disk drive seems to have committed major
sins of omission on his last shutdown. I think the file's probably just
plain gone :-(
