This looks pretty much ready. I'm going to spend some time on this on
Friday, and if all looks good, commit. (Thursday's a public holiday here).
One quick comment:
It would be good to avoid the extra comparisons of the distances, when
the index doesn't return any lossy items. As the patch stands, it adds
one extra copyDistances() call and a cmp_distances() call for each tuple
(in a knn-search), even if there are no lossy tuples.
