 Reporter:  mjurce   |       Owner:  pramsey      
     Type:  defect   |      Status:  new          
 Priority:  medium   |   Milestone:  PostGIS 2.0.4
Component:  postgis  |     Version:  2.0.x        
 Keywords:           |  
---------------------+------------------------------------------------------
 Executing:
 select st_length(st_geomFromtext('CIRCULARSTRING(0 1000,707.1067812
 707.1067812,1000 0)'));

  st_length
 ------------------
  1570.63862548611

 Gives same result as:
 select st_length(st_curvetoline(st_geomFromtext('CIRCULARSTRING(0
 1000,707.1067812 707.1067812,1000 0)')));

  st_length
 ------------------
  1570.63862548611

 The function should return the arc length and not the approximated
 linestring length.
