Thanks for the response. I should have been clearer initially.
I have a PG dump (using pg_dumpall) from a PostgreSQL 7.3.4 server on
Redhat 7.2 that I am trying to restore.
But on the newer machine (I cannot verify if postgres has ever been run
on it or if it did when last), even before I try to restore, I notice
that on startup I get the following error.
[root(at)devdb3 8.1]# service postgresql start
An old version of the database format was found.
You need to upgrade the data format before using PostgreSQL.
See /usr/share/doc/postgresql-8.1.10/README.rpm-dist for more information.
So, even without getting to the restore stage using psql as outlined here:
I would like to fix the above error first.
