     21  1) ST_Intersection(raster, integer, raster, integer) -> raster -- the integer parameters are the band number of the rasters[[BR]]
     22  2) ST_Intersection(raster, raster, integer) -> raster -- default first raster to band # 1[[BR]]
     23  3) ST_Intersection(raster, integer, raster) -> raster -- default second raster to band # 1[[BR]]
     24  4) ST_Intersection(raster, raster) -> raster -- default both rasters to band # 1
