#3774: st_length on compound curve is on linearized geometry
---------------------+---------------------------
 Reporter:  strk     |      Owner:  pramsey
     Type:  defect   |     Status:  assigned
 Priority:  medium   |  Milestone:  PostGIS 2.1.9
Component:  postgis  |    Version:  2.3.x
 Keywords:           |
---------------------+---------------------------
 Reading the code I found that lwcompound_length, which is called by
 lwgeom_length, in turn called by ST_Length, is using a lineraized curve to
 compute the length.

 This is an inconsistency with changes made in 2.1 from fixing #2463

 I dunno how much back we want to go with fixing this last mile.
