#3056: Confusing results from ST_3DDistance
---------------------+------------------------------------------------------
 Reporter:  strk     |       Owner:  pramsey      
     Type:  defect   |      Status:  new          
 Priority:  medium   |   Milestone:  PostGIS 2.2.0
Component:  postgis  |     Version:  2.1.x        
 Keywords:           |  
---------------------+------------------------------------------------------
 If we adopt the semantic of "missing dimensions are filling"
 (#3045) then ST_3DDistance(3d,2d) should always compute the 2d distance,
 rather than arbitrarily set the Z value of the 2d operand to 0.
