login error - Warning: pg_connect(): Unable to connect to PostgreSQL server: FATAL: password authentication failed for user "kamik"

Hi guys,
I am trying connect to Postgres by PHP. I have this PHP code:
 

But web browser writes this error:
Warning: pg_connect(): Unable to connect to PostgreSQL server: FATAL:  password authentication failed for user "***"
FATAL: password authentication failed for user "***" in /var/www/test/index.php on line 6  Warning: pg_last_error(): No
PostgreSQLlink opened yet in /var/www/test/index.php on line 7 Could not connect:  

Main problem is that I have bad authentication for my user. In my pg_hba.conf is this:
# Database administrative login by UNIX sockets
local   all         postgres                          ident
# TYPE  DATABASE    USER        CIDR-ADDRESS          METHOD
# "local" is for Unix domain socket connections only
local   all         all                               trust
# IPv4 local connections:
host    all         all         127.0.0.1/32          trust
host    all         all         0.0.0.0/0             md5
hostssl all         all         0.0.0.0/0             md5
hostnossl all       all         0.0.0.0/0             md5
# IPv6 local connections:
host    all         all         ::1/128               md5

And in postgresql.conf I set listen_addresses = "*"

When I delete in PHP script in pg_connect host="localhost", then all works fine, because I use UNIX domain socket (I am
thinging...), but when I use "normal" connection, it is wrong. Interesting is that phppgadmin works fine ... . 

So, question is what I do wrong. I thing that I have mistake in pg_hba.conf, but I am blind. I have postgresql-8.4



Best regards
