#2422: geography regression difference ST_DWithin
---------------------+------------------------------------------------------
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):
No, simpler, just
{{{
SELECT
someId, _ST_DistanceUnCached(), _ST_DistanceTree()
FROM yourtable
WHERE _ST_DistanceUnCached() != _ST_DistanceTree();
}}}
See? The problem is the algorithms are returning different answers for a
very few example geographies, and this will both isolate the ones that are
failing and give a hint what the different answers are.
