Recently I tried this model from Anita, and it worked very well. Avoid
using too high accuracy values while exploring it, cause the calculation
can take long.

Hi Boaz
I just stumpled across some very nice PostGIS functions few days ago:
http://postgis.net/docs/manual-2.2/ST_ApproximateMedialAxis.html
http://postgis.net/docs/manual-2.2/ST_StraightSkeleton.html
For ST_ApproximateMedialAxis() you need SFCGAL extension installed.
