If I get the idea of pg_result_seek() right, instead of the following script

$result = pg_query($db, $query);
// some outside loop
while ($whatever) {
    for ($i = 0; $i < pg_num_rows($result); $i++) {
        $row = pg_fetch_array($result, $i);
        // do something
    }
}

I should be able to write

$result = pg_query($db, $query);
// some outside loop
while ($whatever) {
    pg_result_seek($result, 0);
    while ($row = pg_fetch_array($result)) {
        // do something
    }
}

The problem is, when I use it this way, it misses the first row (it looks like it iterated from the row nr 1, which is the second row in the result). I even tried to call pg_result_seek($result, -1), but, not surprisingly, it didn't work.
