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.) -- Death to <Redacted>, and butter sauce.
