st_length on compound curve is on linearized geometry
|Reported by:||strk||Owned by:||pramsey|
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.
