PostgreSQL 7.3/RH 9/PGAdmin Not a good combo?

Hi all,
Yesterday, I upgraded my db server to RH9, and as usual with RH updates, it
did not go smoothly. After several hours of 'tweaking', I finally got
everything working again, except now pgadmin crashes whenever connecting to
the database. This happens on every client machine. Here is the log from one
of them.

2003-04-03 10:57:35 - SQL (template1): SELECT version()
2003-04-03 10:57:35 - SQL (template1): SELECT datlastsysoid FROM pg_database
WHERE datname = 'template1'

2003-04-03 10:57:35 -

The object invoked has disconnected from its clients.

Does anyone have any idea what this means or how to correct it? Please help!

Thanks,
