Comment (by robe):
For more fun, I decided to see what would happen if I simplified. Took
15:31 minutes to complete and returned an answer of 4434.16000.
{{{
-- US 12215 pts; Russia 14686
SELECT ST_Distance(ST_Simplify(a.geom,0.01)::geography,
ST_Simplify(b.geom,0.01)::geography) --::geography,
ST_Simplify(b.geog::geometry,0.8)::geography)
FROM (SELECT geom FROM ur_test WHERE name = 'United States') AS a
, (SELECT geom FROM ur_test WHERE name = 'Russia') AS b;
}}}
I also started the old unsimplified running, after 1 hr, 38 minutes and
36 seconds, I still have no idea how far Russia is from US. I'll keep it
running because I really want to know now.
