Sorry, that's not happening for 8.2. Consider using a union all (not
union) across the subledg_N tables directly and then joining to that.
That boils down to being a partitioning case and I think probably will
be covered by the 8.2 improvements. There isn't any understanding of
how to commute joins and unions though ... (offhand I'm not even sure
of the conditions under which such a thing would be safe).
