#840: PointOnSurface strange behavior
------------------------+----------------------------

Hi all,
Using Postgis's ST_PointOnSurface, i've got some weird results in recent
version of Postgis (> 2.0).
See that image :

I would like to know how the PointOnSurface is calculated, and why there
are so much differences between polygon A,B and C.
With Postgis 1.5 it was working fine (i.e. the PointOnSurface for my
polygons were at almost the same place than the Centroids)
Thank you.
Sylvain b.
