to do "service postgresql start/stop/restart" you should be root, not
postgres.


try connecting to the server locally:
[root@]# su postgres
[postgres@]# pslq -d dbname

if you have no databases:
[postgres@]# createdb dbname
[postgres@]# psql -d dbname



if this works but you still have problems connecting over tcpip, look in
  the /var/lib/pgsql/data/postgresql.conf  file and enable tcpip
connections.
