     Type:  defect   |      Status:  new          
 Priority:  medium   |   Milestone:  PostGIS 2.0.5
Component:  postgis  |     Version:  2.0.x        
 Keywords:  curves   |

Comment(by mjurce):

 Considering that the original data to be converted to curved was linear
 and linear geoms comes
 from curved.
 If they had curves before conversion to linear,
 probably they will be not approximated with only 3 points.
 Except the cases with flat arcs.
