Multi-Dimensional Histograms

Folks,

For things like PostGIS, which will want to index in 4 dimensions
(x, y, z, t), we might want to have multi-dimensional selectivity
histograms and some way to use same.

Anybody here qualified to check out this paper on the subject, please
speak up :)

Cheers,
David.
