Comment(by strk):

 For CopyTopology regress test the offending query for the 8.4 case is:
 {{{
 SELECT * FROM "CITY_data_UP_down".node EXCEPT
 SELECT * FROM "city_data".node;
 }}}

 It actually fails for me too on 8.4.8 (succeeds in 8.4.3).
 It is probably related to btree index for geometry. Did its semantic
 change ?
 It used to be bounding box equality.

 Interesting enough it only fails for points, not for edges (which also
 have geometries involved).

 My failure case is on 32bit GNU/Linux and returns all of the 22 nodes from
 the query. In your case a single row is returned.
