The count would count the number of pixel with value (ignoring nodata values). Event if this operation is VERY similar to rescale it could be named ST_Aggregate instead. It would accept a size (in pixel) for the aggregate pixel area and an aggregate type (sum"", ""count"", ""mean"", ""max"", ""min"", ""median""). If the resample code base (based on GDAL) could be reuse or if a totally new function has to be written is to be determined.",enhancement,new,low,PostGIS Fund Me,raster,master,,,
