#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.
