 I was looking at this case:
 https://hub.qgis.org/issues/8572
 and tried to workaround by following the reccomendation of the exception
 message

 {{{
 Antipodal (180 degrees long) edge (180 -90,180 90) detected,
 add a point between to make two edges that span less than 180 degrees.)
 }}}

 But doing so gave a false result:

 {{{
 strk=# with params as ( select st_makeenvelope(-180,-90,180,90,4326) as
 env, 'POINT(0 0)'::geography as g ) SELECT
 st_area(st_segmentize(env,170)), st_area(env) from params;
  st_area | st_area
 ---------+---------
    64800 |   64800
 (1 row)

 strk=# with params as ( select st_makeenvelope(-180,-90,180,90,4326) as
 env, 'POINT(0 0)'::geography as g ) SELECT g && st_segmentize(env,170)
 from params;
  ?column?
 ----------
  f
 (1 row)

 }}}


 What am I missing, Paul ?
