But there is a patchset under development to improve pg_dump's behavior with tons of blobs: https://www.postgresql.org/message-id/842242.1706287466@xxxxxxxxxxxxx That's intended for v17, and I'm not sure how tough it might be to adapt to v15 pg_dump, but maybe you could make that happen. In any case, more eyeballs reviewing that patchset would be welcome. regards, tom lane
