Dear all, I am a novice user, so any help with the following problem would be greatly appreciated. I had Suse 9.1 installed on one hard disk in my machine (/dev/hda). On this machine Postgresql 7.4 was installed and I had one database which, I believe, was installed in the default location This hard disk no longer boots and so I have installed Suse 10.0 on another hard disk in the same machine (/dev/hdb). This OS has Postgresql 8.1 installed and I would like to be able to connect to the database on the old hard disk (/dev/hda) so that I can dump it to make a backup and eventually transfer it to the new hard disk. How should I go about doing this? Are there any problems I should be aware of in moving from version 7.4 to 8.1? thanks, Matthew Henderson
