I'm a NOVICE too.  So take what I say with a grain of salt.

as root
ps -eaf | grep postmaster

will determine if the postgres is working.

The reason you can't connect is due to pg_hba.conf need to be setup correctly.
Since, I don't really understand how to get postgres to use the standard
linux user password file maybe to can post the answer if you get it working.
