Fatal error! Too many clients postgres

[gadaschowdary]

I am using linux with postgres
This is my connection.php file.
So when ever i need connection i include this file at the top of that particular page.


<?php
require_once '/zeus/tsweb/pg.php';
require_once '/zeus/tsweb/defaults.php';
require_once 'session.php';

$pg_hostname_Zeus = "localhost";
$pg_database_Zeus = "b001db";
$pg_username_Zeus = "ts_admin";
$pg_password_Zeus = $pgPassword;
global $Zeus;

//$pgZeus = @pg_close();
$pgZeus = @pg_connect("host=$pg_hostname_Zeus dbname=$pg_database_Zeus user=$pg_username_Zeus password=$pgPassword");
//or trigger_error(pg_error(),E_USER_ERROR);

$pageTopeBgcolor="#ECE9D8";

?>


the error says sth do with pg_session.php

code in that file is this


<?php
function open($save_path, $session_name) {
global $sess_save_path;

$sess_save_path = $save_path;
return(true);
}

function close() {
return(true);
}

function read($id) {
global $sess_save_path;

$sess_file = "$sess_save_path/sess_$id";
return (string) @file_get_contents($sess_file);
}

function write($id, $sess_data) {
global $sess_save_path;

$sess_file = "$sess_save_path/sess_$id";
if ($fp = @fopen($sess_file, "w")) {
$return = fwrite($fp, $sess_data);
fclose($fp);
return $return;
}
else {
return(false);
}
}

function destroy($id) {
global $sess_save_path;

$sess_file = "$sess_save_path/sess_$id";
return(@unlink($sess_file));
}

function gc($maxlifetime) {
global $sess_save_path;

foreach (glob("$sess_save_path/sess_*") as $filename) {
if (filemtime($filename) + $maxlifetime < time()) {
@unlink($filename);
}
}
return true;
}

if(get_cfg_var("session.save_handler") == 'user') {
session_set_save_handler("open", "close", "read", "write", "destroy", "gc");
}

if(get_cfg_var("session.auto_start") == 0) {
session_start();

require_once '/zeus/tsweb/pg.php';
//require_once '/zeus/tsweb/defaults.php';

$pg_hostname_Zeus = "localhost"; //it was 127.0.0.1
$pg_database_Zeus = "zeusV6";
$pg_username_Zeus = "ts_admin";
$pg_password_Zeus = $pgPassword;
global $pgZeus;

$pgZeus = @pg_connect("host=$pg_hostname_Zeus dbname=$pg_database_Zeus user=$pg_username_Zeus password=$pgPassword");
//or die('Could not connect: ' . pg_last_error());

$_SESSION['MAX_ROWS'] = 15; // default lines per page
$pageTopeBgcolor="white";

}
?>
