Обсуждение: Restoring from older pg_dump files
Hello,
I have a data file dumped from a pgsql database version 7.1.2. I am
having troubles restoring this data to a new database server version
8.1.5. Are there some gotcha's involved, did the format change, or some
such?
I have used the createdb command to make the basic database. it's when
I use the \i option in psql that I see invalid commands, syntax errors,
invalid roles, etc.
The original file was created with pg_dump -cou.

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?
