 Priority:  medium         |   Milestone:  PostGIS 2.0.0
Component:  postgis        |     Version:  trunk        
 Keywords:                 |  
---------------------------+------------------------------------------------
 PostGIS 2.0.0 as of 2011-11-08

 {{{
 SELECT ST_AsText(ST_Segmentize(ST_GeomFromText('LINESTRING(1 2,1 2)'),
 100))
 }}}

 returns "LINESTRING(1 2)", which is invalid - parsing it with
 ST_GeomFromText() fails. I would expect it to return the input value
 ("LINESTRING(1 2,1 2)").
