$conn=pg_connect('host='.$dbhost.' dbname='.$dbname.' user='.$dbuser.' password='.$dbpass); 
if (!$conn) {
  echo "An error occured.\n";
  exit;
}else{

        $insert=pg_query($conn, "Insert into `advertiser_regidetdir` 
        (user_name,domain_name,user_email,publickey,privatekey, refresh_count )
        values('$user','$domain','$email','$pubkey','$pritekey',0)");
