-Josh,
i don't be so thrilled:), with current implementation of /contrib/tablefunc
mine problem sill remains: i need to sort tree leaves in some order,
independent of tree itself. this can be fixed (in tablefunc) by addition to
connectby() one more field like 'order_by' or so. but it will be more difficult
to scale. for ex. if i need to make subquery with connect by, with tablefunc
i need to create view to do so. what if i need several different such
queries? of course this can be done with tablefunc, but IMHO mine
approach is a bit more 'native':)
