Found a python version here for minimal area enclosing rectangle

It takes a numpy 2D array as point
That means it is possible to use shapely to read postgis wkb geom, then
convert it to numpy and
And if you do that on the convex hull rather than the original geometry,
you will have less points to consider while doing the evaluation.

Convex hulls are not only needed as a performance boost. You would need
some complicated find next extreme point-code in order for the algorithm
to behave correctly as well.

Of course I plan to use convex hull,
I didn't put it because I can call it at plpgsql level so I consider it to
be free.
