 Priority:  medium   |   Milestone:  PostGIS 2.0.4
Component:  postgis  |     Version:  1.5.X

 It looks like you can't convert a 2-points line to a curve, but the
 message is not friendly:
 {{{
 ERROR:  pta_desegmentize needs implementation for npoints < 4
 }}}

 Should the code aim to return a COMPOUNDCURVE containing a single
 linestring in these cases ? That's what would cleanly convert back to the
 original input

 Affected versions from 1.5.x to 2.2
