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!
