#3779 closed patch (fixed)

ST_Boundary(curvepolygon) returns a linearized boundary

Description

I see no reason why ST_Boundary should linearize curves, but this is what happens at the moment. Maybe it's because we delegate to GEOS such a simple operation. This ticket is to do it on our side, to retain curves.

NOTE: ST_ExteriorRing behaves correctly (my case is polygons..)
