I think you need to upgrade your PHP versoin.
I'm using 4.2.0-dev/PostgreSQL 7.1.3. I do not
have problem at all with following script.
<?php
$db = pg_connect('user=yohgaki');
$res = pg_query("SELECT * FROM pg_class");
$fn = pg_field_num($res, 'reltype');
echo 'Field num is '.$fn."\n"; // $fn is 1
$res = pg_query("SELECT 1 AS one");
$fn = pg_field_num($res, 'one');
echo 'Field num is '.$fn."\n"; // $fn is 0
?>
