[GENERAL] [PHP] How to connect to PostgreSQL with phpPgAdmi

For the phpPgAdmin users, if you might help!!!....

I am running PostgreSQL 7.1 over RedHat.

When trying to connect through the web everything goes right. A script that is currently working:

<?php

$link = pg_Connect("host=localhost port=5432 dbname=teste")
or die ("Could not connect");

    $comando = "select * from teste";
    $result = pg_exec($link,$comando);
    $linhas_retornadas = pg_numrows($result);

    echo "<table><td><b>nome</b></td><td><b>sobrenome</b>";
    for ($i=0; $i < $linhas_retornadas; $i++) {
      $row=pg_fetch_array($result,$i);
      echo "<tr><td>" . $row["nome"] . "</td>";
      echo "<td>" . $row["sobrenome"] . "</td></tr>";
    }
    echo "</table>";

pg_close ($link);
?>

All *my databases are owned by user 'postgres'* and I had to create another PostgreSQL *user 'apache' and give ownership of table 'teste' in database 'teste' to this user* (apache) in order for this connection to work.

My 'pg_hba.conf' file reads:
local all trust
host all 127.0.0.1 255.255.255.255 trust

With phpPgAdmin I configured file 'config.inc.php' as follows:

// The default database is used to connect to the database to check the adv_auth
//      This can actually be any database you currently have on your system. It just
//      needs _a_ database to connect and check the system tables.
$cfgDefaultDB   = "teste";

// You should change the superuser if different from postgres
// This is just used to filter out the system functions when listing
$cfgSuperUser = "postgres";

// Set to true if you want to authenticate against the passwd as well as the username
//       In order to use adv_auth, you must update the passwords in the user admin section.
//       It is suggested that you leave this as false until you are able to get in and update the passwords.
$cfgUsePass             = false;
$cfgServers[1]['local']         = true;
$cfgServers[1]['host']          = 'localhost';
$cfgServers[1]['port']          = '5432';
$cfgServers[1]['adv_auth']      = false;
$cfgServers[1]['stduser']       = 'apache';

No matter if I set
$cfgServers[1]['host'] as 'localhost' or as '127.0.0.1'
$cfgServers[1]['stduser'] as 'apache' or as 'postgres' or as none

No matter what I always get a blank Web page with the following messages:

================
ERROR

While trying to retrieve the URL: [no URL]

The following error was encountered:

The system tables in PostgreSQL are as follows:

teste=# select * from pg_user\g
usename | usesysid | usecreatedb | usetrace | usesuper | usecatupd | passwd | valuntil
----------+----------+-------------+----------+----------+-----------+----------+----------
postgres | 26 | t | t | t | t | ******** |
apache | 27 | f | f | f | f | ******** |
(2 rows)

teste=# select * from pg_shadow\g
usename | usesysid | usecreatedb | usetrace | usesuper | usecatupd | passwd | valuntil
----------+----------+-------------+----------+----------+-----------+--------+----------
postgres | 26 | t | t | t | t | |
apache | 27 | f | f | f | f | |
(2 rows)

Please help!!! This shall most probably be some problem of permission, but how do I manage to make phpPgAdmin to correctly connect and access my databases?

TIA,
Paulo
