    192 List of functions implementable based on the two raster version of map algebra:
    193 
    194  * ST_Intersection(raster, raster) See at the end of [http://trac.osgeo.org/postgis/browser/trunk/raster/scripts/plpgsql/st_mapalgebra.sql plpgsql/st_mapalgebra.sql]
    195  * ST_Union (raster, raster) not the aggregate one. See at the end of [http://trac.osgeo.org/postgis/browser/trunk/raster/scripts/plpgsql/st_mapalgebra.sql plpgsql/st_mapalgebra.sql]
