Changes between Initial Version and Version 1 of Ticket #12314, comment 1

initial	v1
1		In non-cartesian ~~CSes the edges of Polygons are~~ shortest lines between points so e.g. the edge: `(0 89, 180 89)` intersects the north pole. In the case of the edge `(180 0, 0 0)` I'm not sure what the algorithm assumes but this edge is invalid. The reason for that is that there is infinite number possible edges connecting these points in spherical and 2 possible edges in geographic (going through north or south pole). Either way I presume this is not what you had in mind.
	1	In non-cartesian coordinate systems the edges of Polygons are also shortest lines between points so e.g. the edge: `(0 89, 180 89)` intersects the north pole.

3	3	You could fix the invalidity by adding additional point between the invalid edge, so: `POLYGON((0 89, 180 89, 180 0, 90 0, 0 0, 0 89 ))` but this is not what you wanted to do either.
