You mean the server actually starts with the command 'su -postgres' ? Weird.
Start command should be something like this (as postgres):
/usr/local/pgsql/bin/postmaster -D /usr/share/pgdata &

With '&' you don't have to open another terminal, just press enter and your at
prompt again.

Then I open up another terminal

So maybe RHEL3 really starts the server with that. The error comes because you
already have started it. Anyway, you can ignore the message, I believe it
won't do anything as it is already running.

As postgres you are creating a database user, not a system user ? So you can
not su databaseuser, ie. become that user on the system itself (su is for
substitute user). This user could however connect to a db via php or some
other interface. If given rights to do so in pg_hba.conf.

RHEL 3 obviously is not same as RH 9. Anyway, I hope this helps.

And for later on, you might find this helpful (the bit about upgrading PgSQL):
