#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 robe):
Let me try that once more -- my memory buffer is giving me problems:
{{{
SELECT COUNT(*) FROM face
WHERE _ST_DWithin(geog, st_setsrid(st_makepoint(-71.0636, 42.3584),
4326)::geography, 1609.344,true );
}}}
yields this:
{{{
count
-------
395
(1 row)
Time: 110076.840 ms
}}}
thus conclusion _ST_DWithin(geography, geography,dist, use_sphere) has
got some issues.
I vaguely remember having this issue with geometry _ST_DWithin/ST_Distance
you fixed. I'll try to dig up the ticket for that one.
