Comment(by strk):

 @robe I'm talking about the function GeometryType(). There's no such
 function taking TOpoGeometry so what happens is an implicit cast is
 engaged, which is slow if all you need is knowing the type (which is in
 the TopoGeometry value itself...)

 Same applies to ST_GeometryType() but QGis is using the old GeometryType()

 Dunno what a call to GeometryType(myTopoGeometry) would end up calling if
 "topology" schema isn't in your search_path and the override is
 topology.GeometryType().
