#5314: Implement ST_Extent( TopoGeometry )

-------------------------+-----------------------------
 The aggregate could collect identifiers of the TopoGeometry objects by
 topology and layer and in the final function select the extent of the
 components. It'd need to be tested if it's really going to be faster as
 it's still a lot of queries in the db, but the idea is to improve the cost
 of such operation by avoiding to construct the Geometry from the
 TopoGeometry.
