Comment:

 The option I see is to perform either
 https://postgis.net/docs/ST_ChaikinSmoothing.html or
 https://postgis.net/docs/manual-dev/ST_CatmullRomSmoothing.html to give
 the line more points so that interpretation of curvature is less
 surprising. Additionally look at hot new https://postgis.net/docs/manual-
 dev/ST_MakeNurbsCurve.html. Otherwise it is not clear how to implement
 this, if you wish to contribute a patch you're welcome to do it.
