Re: Problem Upgrading from 8.0 to 8.1 (WinXP) ...not still solved!!

when upgrading pg from 8.0 to 8.1 you will have to recreate your databases
and restore your data. the db files are not compatible. there is an easy
tutorial/explanation section in the documentation on "upgrading a db".

basically the steps are the following:
1. while having 8.0 running, dump your databases (pg_dump)
2. install & set-up 8.1
3. restore your databases (pg_restore) into 8.1

good luck,
thomas
