Restart trouble

Hi,

I got in a situation that is strange and i hope some of you could help me out on this.

What I did is kinda simple, I added a post to pg_hba.conf which is
to give access to another user.

After that i run command:


It says [OK]

But when i try to access the website i get this error:

could not connect to database

Please, I need some help to get the website back again, did I do something wrong? Or do I need to restart the server itself as well? This is an bigger database running lvs cluster

Best regards,
Mikkel

Some additional information, it says that it is online:


8.3 main 5432 online postgres /var/lib/postgresql/8.3/main /var/log/postgresql/postgresql-8.3-main.log


But still can't access db or see the site
