Greetings, after a hdd failure, I have a PostgreSQL DB restored, but OS is not working. I try to copy it to another server with a newer version of PostgreSQL but all I managed to get is:
An old version of the database format was found. You need to upgrade the data format before using PostgreSQL. See /usr/share/doc/postgresql-8.1.22/README.rpm-dist for more information.
I don't know the old version number.
Please, advice me something.
