what postgres connection parameters are you passing to the php
connection function?  if you specified host=localhost, or some such,
then on psql use -h localhost to simulate this.

Hi John,

Thanks for your response.

I am able to connect to the database through psql command. Please find
the commands that I have tried through PHP and no success for past 3
days.
Please let me know whether you can help me in this issue.

<?php
ini_set('track_errors','on');
// attempt a connection
$dbh = pg_connect("host=/tmp/ dbname=test_tool port=5495 user=apache
password=apache connect_timeout=20");
// $dbh = pg_connect("host=localhost port=5495 dbname=test_tool");
// $options = " host='localhost' port='5495' user='gls' password=''
dbname='test_tool' ";
// $dbh=pg_connect($options);
if (!$dbh) {
    die("Error in connection: " . pg_last_error($dbh));
print_r($dbh);
}

else
{
echo "Connection is success";
}

?>

Some questions:
1) What is the connection string are you using for psql?
2) How are you connecting in each case(PHP,psql), remotely or locally?
3) What is listen_addresses set to in postgresql.conf?

I am connecting the psql from local and PHP from remote system. I was
also able to access the postgres from the same system using C program

> 3) What is listen_addresses set to in postgresql.conf?

I am running the postmaster with

postmaster -i -D /path

I am running with the following version and I dont have the privilege
to update the existing versions.  listen_addresses option is not
available in the existing version

postmaster (PostgreSQL) 7.4.2
PHP 5.2.6

Today I found one issue.. where I was not able to run the postmaster
with -h option ( that is not other than localhost)

The error what I got is that it was not able to create the listening
socket.

LOG:  could not bind IPv4 socket: Can't assign requested address
HINT:  Is another postmaster already running on port 5496? If not,
wait a few seconds and retry.
FATAL:  could not create listen socket for "IP address"

Please help me to resolve the issue. I dont have root privilege to
access the system

Thanks,
Shankar

I don't know if this will help, but you have port 5496 here, and port
5495 in your psql command above.

Also, PostgreSQL 7.* is VERY old, and as far as I know is no longer
being maintained - so if you're being bitten by a bug, it's probably not
going to get fixed. You should upgrade if you can, or move to a
different service provider if you can't.

Ray.

Well in a previous post you indicated your connection strings for the PHP code
where:

$dbh = pg_connect("host=/tmp/ dbname=test_tool port=5495 user=apache
password=apache connect_timeout=20");
// $dbh = pg_connect("host=localhost port=5495 dbname=test_tool");
// $options = " host='localhost' port='5495' user='gls' password=''
dbname='test_tool' ";


The above would not work if you are trying to connect to a remote server. The
first tries to connect to a local socket and the other two are attempts to
connect to localhost.  Your host would need to be the hostname(ip address) of
the host that the Postgres server is running on.

This would seem to indicate what the HINT says, that another  Postgres server is
running.
