 Dear all,

 I developed for my own needs a ST_MakeEllipse function.
 As it's name said, it returns a polygon with an ellipse shape.
 It takes 4 arguments:
 - the first is a point geometry on wich the ellipse will centered,
 - the second is the length of the main radius of the ellipse
 - the third is a percentage corresponding to the length of the ninor axis
 regarding the major axis length, i.e. minor axis length = major axis
 length x third argument
 - the fourth one is the number of points used to defined the polygon.
