Re: Upgrading from 7.4 to 8.2

Hi Rickard!

As far as i know you will have to dump and restore the databases for the
upgrade since a lot of internals have been changed from 7.4 to 8.2.
A description on how to upgrade can be found here:
http://www.postgresql.org/docs/8.2/interactive/install-upgrading.html
And here: http://www.postgresql.org/docs/8.2/interactive/migration.html

Good luck!

Greetings,
Matthias
