One thing that's probably biting you is that 8.1 defaults to WITHOUT OIDS, which is not an option 7.1 pg_dump even knows exists, so it's not going to say WITH OIDS in the create commands, and then the COPY WITH OIDS commands will fail ... I concur with Josh's to use the newer version's pg_dump, but if you can't, setting default_with_oids = true will probably help. There might be some lesser gotchas too --- what sorts of errors do you get exactly after fixing that? regards, tom lane
