Comment (by nicklas):

 I just noticed that ~= is defined in postgresql too. As I read it there is
 the same definition as postgis of today that the geometries should be "the
 same" to return true even if the example given, makes me quite confused if
 the order of vertexes matters or not.

 http://www.postgresql.org/docs/8.4/static/functions-geometry.html

 just a note toplans of changing ~= to just compare bboxes from the
 discussion above.
