In an earlier post, I mentioned that PG Lightning Admin seemed to hang when I did a dump. Mr. Caduto provided some help with this and the problem was resolved by setting my connection to "trust" in hba.conf.
Regarding Chilli Source Database Design Studio, I downloaded a trial copy and when I tried to "reverse engineer" my PostgreSQL database, got an error that pg_relcheck doesn't exist. Since pg_relcheck isn't used in PostgreSQL 8.0, perhaps the Chilli Source program hasn't been updated?
btw, another program that isn't bad is DBTools Manager.
