     Type:  defect   |      Status:  new          
 Priority:  medium   |   Milestone:  PostGIS 2.0.0
Component:  postgis  |     Version:  trunk

---------------------+------------------------------------------------------
 This is doing regression between our current 1.5.3 and 2.0.0.  I haven't
 tested our older 2.0.0 yet to see if it was introduced during change to
 gserialize.

 This fails in current 2.0.0 trunk but just returns an empty string in 1.5.


 {{{

                         UNION ALL SELECT ST_GeomFromText('POINT
 EMPTY',4326) As the_geom ) ) As foo1 LIMIT 3;
