Comment(by pramsey):

 The function has to hit the distance function twice to get the caching to
 kick in and thereby hit the tree. You can skip the cache by calling
 _ST_DistanceTree(geog, geog) directly for testing, and it goes boom:
 {{{
 select _st_distancetree('LINESTRING(-60.1529985502867 -3.00511933469609,
 -60.1529985502867 -3.00511933469609)'::geography, 'POINT(-60.1529903235046
 -3.00464549022075)'::geography);
 }}}
