#2831: ST_Orientation only applies to polygons and generally needs work

 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.
