ST_Orientation only applies to polygons and generally needs work

[robe]

I assume this is a documentation mistake. This function is flagged as supporting polyhedral surfaces and what not, but when I do this:

SELECT ST_Orientation(ST_Extrude(ST_Buffer(ST_Point(1,2),5), 0,0,-5));

I get :

ERROR:  orientation() only applies to polygons

Also what exactly does the integer output mean. It's not defined anywhere what these units are.
