 Just stripping the example down to a smaller one for the debugger
 {{{
 SELECT
         _ST_DistanceTree(g1, g2),
         _ST_DistanceUncached(g1, g2)
 FROM
         (SELECT
                 ST_Transform(ST_GeomFromText('POLYGON((-5  0, -5 100, 5
 100, 5 0, -5 0))',32641),4326)::geography AS g1,
                 ST_Transform(ST_GeomFromText('POLYGON((-10  30, -10  40,
 -20  40, -20  30, -10  30))',32641),4326)::geography AS g2
