[postgis-devel] ST_OrderingEquals what does it do

[Obe, Regina]

I was preparing examples for the docs and was surprised to find this returns false
SELECT ST_OrderingEquals(ST_GeomFromText('LINESTRING(0 0, 10 10)'),
  ST_GeomFromText('LINESTRING(0 0, 5 5, 10 10)'));
 
Evidentally I don't understand how Ordering Equals works.  I assumed since the above returns
true for ST_Equals and the line is in the same direction, the above would return true as well.
 
Thanks,
Regina
