Comment(by pramsey):

 Wondering where to document them? I don't want them to be used by users,
 is it still OK to put them it the users manual ( we don't for example have
 documentation on _ST_Intersects, if I'm not mistaken).

 Also, there is a static function (nd_stats_to_grid) to print out the first
 2D histogram, but it's not tied to SQL right now. Your talk about
 outputting to raster got me interested, but I didn't actually do it (a
 raster expert like yourself on the other hand..?)  And of course, ideally
 we'd be able to output the N-D histograms, but I'm not sure what the best
 way to expose that is, given the limitations of our brains/media.
