Thank you, I would have never guessed. $ pg_dump -V -h x pg_dump (PostgreSQL) 17.4 (Ubuntu 17.4-1.pgdg22.04+2) $ pg_dump -V pg_dump (PostgreSQL) 12.20 (Ubuntu 12.20-0ubuntu0.20.04.1) (facepalm) I was using the latter checking what pg_dump version was actually being used. Wasn't aware of this pg_wrapper business. > Given a pg_dump, it would be nice if its "-V" output would say which > version of the dump it would produce Yeah, this wouldn't have helped a bit.
