Did you use synaptic and try "Mark for Complete >Removal"?  Did you 
remove all of the postgresql packages?  I'm just guessing that if you

Yes, I was using synaptic. It showed there were no instances of 
postgresql left. I finaly found an answer after more searching.

This will give you a clean slate:
apt-get --purge remove postgresql-8.3 postgresql-client-8.3 
postgresql-client-common postgresql-common

mv /var/lib/postgresql /var/lib/postgresql-backup
mv /etc/postgresql /etc/postgresql-backup
mv /var/log/postgresql /var/log/postgresql-backup
apt-get install postgresql-8.3 etc..

I'm back to where I started, with my problem being the new app, and a 
working instance of postgresql.
