#2062: Performance Drop in ST_Distance(geog)
 Reporter:  pramsey  |       Owner:  pramsey      
     Type:  defect   |      Status:  new          
 Priority:  medium   |   Milestone:  PostGIS 2.0.2
Component:  postgis  |     Version:  2.0.x        
 Keywords:           |  
 Versions 2.0+ included a change in the distance code that results in
 repetitive calculation of the geocentric bounds of objects during distance
 calcs. This can cause much longer return times. See #1976, comment #7.
