#1757: Spheroid length functions returning unexpected results.
 Reporter:  darkpanda  |       Owner:  pramsey      
     Type:  defect     |      Status:  new          
 Priority:  medium     |   Milestone:  PostGIS 2.0.1
Component:  postgis    |     Version:  2.0.x

Comment(by darkpanda):

 Ah, okay. That makes sense then, albeit unexpected, as the docs page for
 ST_3DLength_Spheroid doesn't mention this and still refers to the old
 behaviour saying "Will return 0 for anything that is not a MULTILINESTRING
 or LINESTRING", so that should probably be updated.

 I also notice that on the docs page for ST_3DLength_Spheroid, the docs say
 that "in prior versions this used to be called ST_Length_Spheroid3D", but
 I believe the older name for this function was ST_Length3D_Spheroid.
