This would be a lot easier to read and also safer if you used prepared
statements (see http://www.php.net/manual/en/function.pg-prepare.php), e.g.

$result =         /* no tedious quoting */
    pg_prepare($dbconn, "my_query",
    'insert into timmar(pack_date, pack_tidut) values ($1, $2)');


$result = pg_execute($dbconn, "my_query", array($pack_date, $pack_tidut));
