Comment (by mdavis):

 I will also note that the LostGIS approach doesn't help with aggregate
 ST_Union as it stands.  But it might be worth looking at their approach to
 see if it can be incorporated.  Although the new overlay code should solve
 this problem anyway, so perhaps that will arrive first.
