     Type:  defect   |      Status:  new          
 Priority:  medium   |   Milestone:  PostGIS 1.5.6
Component:  postgis  |     Version:  1.5.X

 Example
 {{{
 select st_distance(st_makeline(ARRAY['POINT(1 1)'::geometry]), 'POINT(0
 0)'::geometry);
 }}}
 In the interests of tolerance and interstellar peace, it should maybe
 return the distance from the one point to the other.
