Re: Password?

Hi,
 
I started everything again from scratch.
1. Created a new user("Swati"), with limited/ restricted rights.
    Ensured that no password is set anywhere.
 
2. Ran initdb from the new user.
            c:\postgresql\bin>initdb -D c:\postgresql\data2
       It displayed the DEBUG: start transaction and commit transaction states etc.
       and ended with DEBUG: exit(0)
       A warning with the following statement was also displayed:
             WARNING: enabling "trust" authentication foe local connections
             you can change this by editing "pg_hba.conf" or by initdb -A.
 
3. After this I executed pg_ctl:
             c:\postgresql\bin>pg_ctl -D c:\postgresql\data2 -l logfile start
             got the the message:server starting
             and the logfile contained the following:
                 LOG:  could not bind IPv4 socket: No error
                 HINT:  Is another postmaster already running on port 5432? If not,
                 wait a few seconds and retry.
                 WARNING:  could not create listen socket for "localhost"
                 FATAL:  could not create any TCP/IP sockets
                 LOG:  could not bind IPv4 socket: No error
                 HINT:  Is another postmaster already running on port 5432? If not, wait
                 a few seconds and retry.
                 WARNING:  could not create listen socket for "localhost"
                 FATAL:  could not create any TCP/IP sockets
 
4. To take care of the above issues,
         Made the following change in the postgresql.conf file:
                 listen_addresses = 'xxx.xxx.x.x' (my current ip)
         and in pg_hba:
                 host all all 'xxx.xxx.x.x' trust
 
5.Then issued
         c:\postgresql\bin>pg_ctl -D c:\postgresql\data2 -l logfile start
   again.
   Now got the following in logfile:
                 LOG: database system was shut down at 2009-07-08 22:34:50
                 LOG: database system is ready to accept connections
                 LOG:  autovacuum launcher started
 
6.Opened another command window.
   Now when I write in the new window (or even in the same),
                 c:\postgresql\bin>createdb demo
   OR
                 c:\postgresql\bin>createuser -S -d -R svc
   I am prompted for password, I don't know what to enter here.
 
I think I am making some mistake in pg_hba.conf. Can't make out.
Must be some brainless blunder some where.
 
Thanks a ton for sparing your time and bearing with me.
 
Please guide.
 
Regards
Swati
