Version information:

postgresql: 8.1.4

I've tried to set the dbmode to 'multi' like described in http://de.php.net/manual/en/function.udm-alloc-agent.php, but it won't work. All I'll get are empty results.

Reproduce code:
---------------
<?php
error_reporting(4095);
ini_set('display_errors', 'On');
define('UDM_DBADDR', 'pgsql://user:password@/database/');
define('UDM_DBMODE', 'multi');
$agent0 = udm_alloc_agent(UDM_DBADDR, UDM_DBMODE)
    or die("Wrong argumnets for agent0");
$agent1 = udm_alloc_agent(UDM_DBADDR.'?dbmode=multi',
    'Insert whatever you like, or not, except NULL.')
    or die("Wrong argumnets for agent1");
udm_set_agent_param($agent0, UDM_PARAM_WORD_MATCH, UDM_MATCH_BEGIN);
udm_set_agent_param($agent1, UDM_PARAM_WORD_MATCH, UDM_MATCH_BEGIN);
$res0 = udm_find($agent0, 'bugreport');
$res1 = udm_find($agent1, 'bugreport');
printf("Result0 contains %d matches\n", udm_get_res_param($res0,
    UDM_PARAM_NUM_ROWS));
printf("Result1 contains %d matches\n", udm_get_res_param($res1,
    UDM_PARAM_NUM_ROWS));
?>

Expected result:
----------------
Result0 contains 5 matches
(max:) Result1 contains 0 matches
(min:) notice or warning

Actual result:
--------------
Result0 contains 0 matches
Result1 contains 5 matches
