there are nicer ways (look for one in the db-abstraction layer in PHP-LIB)
but this works:

> $qu = pg_exec ($db_conn, "SELECT * FROM clients ORDER BY username");
$number_of_rows = pg_numrows($qu);
for ($counter=0;$counter<$number_of_rows;$counter++) {
    $data_array = pg_fetch_array($qu, $counter);
    echo "$data_array[username]";
    }
