Higher dimension support for ST_ClosestPoint
|Reported by:||strk||Owned by:||pramsey|
When you look for "the closest point" I think you want a point with all dimensions in it. At least Z, if the first geometry had one.
What's the closest point to 'POINT(6 0)' on 'LINESTRING(0 0 0, 10 0 40)' ?
I think it should be 'POINT(5 20)', and not 'POINT(5 0)'
