Description
It would be nice to use a geometry to filter a raster and then compute the statistics for the filtered raster.
These functions would probably be built upon ST_Intersection and kept in plpgsql unless it is found that performance is lacking.

I'll keep it for now. Once aggregate versions of the stats functions are done, this is worth revisiting...
Note:
See TracTickets
for help on using tickets.
I would say that now that we have a C version of ST_Clip, we don't really need this option anymore. Up to you to keep or close it. Would be a lot of work in many stats functions.
