-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.
Ah, so the culprit is "-v". I like using -v, redirecting it to a log file (more info is almost always better), but then I rarely use pg_dump, and never pipe it to de-duplicators. (ExaGrid is supposed to deduplicate, but that's not going to stop me from using pgbackrest, compression and encryption; PCI auditors care about that, not deduplication.)
