  This function should be implemented as a pl/pgSQL function (possibly only a SQL function) performing the intersection between the provided geometry and the table generated by ST_AsPolygon(raster).
 
+ Priority 1 should be given to the raster/geometry variants (original and variant 1) returning a geometry.

+ Priority 2 should be given to the raster/raster variants (5) returning a geometry.

+ Priority 3 should be given to the other variants (2, 3 & 4) returning a raster. Variant 2 & 3 should be implemented after the planned ST_AsRaster(geometry) function. What should be the raster result of the intersection of two rasters is still to be specified.
