Used to work with 3.0.7.

$q = "select ...";
$res = pg_exec($db, $q);
for ($n = 0; $res && $n < pg_numrows($res); $n++) {
	$arr = pg_fetch_array($res, $n);
	# some echos displaying $arr[name], $arr[descr]...
}

first record is displayed ok ($n == 0), the others are empty.
This bug shows with 3.0.10 and 3.0.11, reverting to 3.0.7
solves it. 3.0.1[01] were compliled exactly the same way of 3.0.7 (i just
recompiled it to be sure).
I haven't tested 3.0.[89].
