+2) Log into your server as root, and then type:
+
+[root@localhost ~]# su - postgres
+
+This will log you into the system as the "postgres" user, so that you can
+create a new role and database within the PostgreSQL database system.  At the

+Obviously you should enter a password when prompted.  This creates the

+Next we need to create the asterisk database.  Type:
