Bug reference:      1088
Logged by:          Antonino Albanese

PostgreSQL version: 7.4

Operating system:   Linux server.sitvallee.it 2.4.20-28.7smp #1 SMP Thu Dec 
18 11:18:31 EST 2003 i686 unknown 

Description:        Name resolution connecting to a database 

Details: 

I'm using postgresql 7.4.1 exactly the rpm version:
[EMAIL PROTECTED]:~$ rpm -qva|grep -i postgresql
postgresql-docs-7.4.1-1PGDG
postgresql-devel-7.4.1-1PGDG
postgresql-contrib-7.4.1-1PGDG
postgresql-server-7.4.1-1PGDG
postgresql-libs-7.4.1-1PGDG
postgresql-7.4.1-1PGDG
postgresql-pl-7.4.1-1PGDG

on a 7.3 RH Server:
Linux server.sitvallee.it 2.4.20-28.7smp #1 SMP Thu Dec 18 11:18:31 EST 2003 
i686 unknown 

all the tests where done directly on the database
server, but I've got the same behavior from different
clients, either using psql or the php interface

trying to connect to the server with domain name
takes long time, here an example:
[EMAIL PROTECTED]:~$ time psql -h server -d newtestdb -U download -c '\q'

real    0m10.151s
user    0m0.010s
sys     0m0.000s

but every thing works fine if I use the IP address:
[EMAIL PROTECTED]:~$ time psql -h 192.168.0.1 -d newtestdb -U download -c '\q'

real    0m0.023s
user    0m0.000s
sys     0m0.020s

here the content of my configuration files:
------------------------------------
