I don't know of anything much you can do at the user level.  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@sss.pgh.pa.us

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.
