#2034: ST_3DClosestPoint with mixed dimensionality in input values
-------------------------+--------------------------------------------------

Component: postgis | Version: trunk

In the example in #2034, there is input of 2d and 3d. ST_3DClosestPoint
then by design assumes that the 2d value have a zero Z-value. But I guess
it is more like undefined.
So I think that the most correct solution maybe is to handle the POINT(6
0) in ST_3DClosestPoint function as a infinite vertical line crossing
POINT(6 0). Then the answer would be what strk expects in #2032.
I want feedback before I try to do anything about it.
