Hi.
With PostgreSQL select result DLL not work.

Warning: call_user_func() expects parameter 1 to be a valid callback, function 'pg_fetch_field' not found or invalid function name in C:\Apache24\htdocs\TestSystem\DLL.dBug.V0.2.php on line 305
Code example:

$QQString = "SELECT * FROM public."TestTable"";
$SQL_Result = pg_query($DBlink,$QQString);
