Comment(by strk):

 I've added some debugging lines but cannot understand what I'm seeing:
 {{{
 pg22=# with params as ( select st_makeenvelope(-170,-80,170,80,4326) as
 env, 'POINT(0 0)'::geography as g ) SELECT g &&
 st_segmentize(env::geometry,0.1) from params;
 NOTICE:  Boxes have dims 3 and 3

  ?column?
 ----------

 }}}

 Where do those numbers (1,-1,0.173648) come from ?
