I've installed pgAdmin3 in my CentOS6. I am using PostgreSQL9.
My problem is that I'm not able to add a server to the pgAdmin3. It gives me an error:


I have not a password for the user "postgres" but I've created a postgresql user just like my regular linux user and I'm able to use "psql":
[andre@andre ~]$ psql
psql (9.0.4)
Type "help" for help.
andre=> \q
[andre@andre ~]$
My question is: How can I use pgAdmin3 in CentOS6. there is any trick? I must to enter with the user "postgres"?
Give me a clue.
Best Regards,
