#2422: geography regression difference
---------------------+------------------------------------------------------
Reporter: robe | Owner: pramsey
Type: defect | Status: new
Priority: high | Milestone: PostGIS 2.1.0
Component: postgis | Version: 2.1.x
Keywords: |

Comment(by pramsey):
It might be hard to find the exact differences because this is going to be
a difference between the tree distance and the edge distance algorithms,
and the tree distance gets turned on as caching goes active. Replace
testing ST_Dwithin with testing for differences between
_ST_DistanceUnCached and _ST_DistanceTree to avoid cache effects.
