Major OS version upgrades don't transparently do database upgrades. You have
to take care of things like that yourself.
In particular, for PostgreSQL, you would need to dump all your databases
using 8.3, then upgrade, then create a new 8.4 installation and restore the
databases into it. Sadly PostgreSQL does not do in-place major version
upgrades.
In your case, you need to stop and make a couple good filesystem-level
backups of your database. Then you need to find a way to either get 8.3
working on that machine, or move the database to another machine where you
can get it working, so you can do the PostgreSQL backup. Then you can think
about getting 8.4 setup on your upgraded machine and restore that backup
into it. You should probably also read through the 8.4 release notes to see
if you will require changes in any applications using those databases.
