#3264: Spurious edges in ST_ApproximateMedialAxis

Comment (by vmo):
Maybe checking the result would be better/easier to find a good tolerance.
The medial axis points should all be at the same distance from the
contour, so checking the distance of Approx Medial Axis segments ends and
middle would provide a metric of the quality (min/max ~ 1, looking at the
picture it would be ~ .5).
