Description:
------------
pg_lo_open() doesn't return a result ressource in php 4.3.2 whereas the same script runs properly with PHP 4.3.1 

Reproduce code:
---------------
<?php
include("lo_lib.php");

$sql = "select * from bilder";
$res = pg_query($sql);
$rows = pg_numrows($res);

for ($i=0;$i<$rows;$i++) {
  $zeile = pg_fetch_array($res,$i);
  echo 'Dateigroesse: '.$zeile["size"];
  pg_query("begin");
  $handle = pg_lo_open($zeile["bild"], "r");  echo '<br>handle = '.$handle.'<br>';
  if ($handle) {
    $data = pg_loread($handle, 50000);
    $len = strlen($data);
    echo ' | gelesen: '.$len.' Bytes';
  }
  pg_loclose($handle);
  pg_exec("commit");
...

Expected result:
----------------
Dateigroesse: 6038
handle = Resource id #6
| gelesen: 6038 Bytes | geschrieben: 6038 Bytes


This is the result from PHP 4.3.1

Actual result:
--------------
Dateigroesse: 6038
handle =
