Yeah, exactly.
Maybe I can obtain it using a succession of functions already
implemented like ST_ConvexHull, ST_ShoortestLine, ST_LongestLine....
But I don't know the algorithm to use, just guessing...
I saw also the routine ST_MinimumBoundingCircle, maybe I need a
simplified version of that...
Any hints?
