(Since isn't it supposed to be Bad to rely on > OIDs?) -v in a text-format dump includes that data for debugging purposes: -- -- TOC entry 1401 (class 1255 OID 16499) -- Name: fipshash(text); Type: FUNCTION; Schema: public; Owner: postgres -- (The "TOC entry" comment line wouldn't be there without -v.) Then custom format has to store the same info so that pg_restore can produce this identical text output on demand. Yeah, this is all pretty historical, but nobody wants to change it at this point. regards, tom lane
