Comment(by strk):

 See also #3056 for related discussion about mixed dimensions in
 ST_3DDistance.
 According to the recent settlements (missing dimensions are infinite) an
 ST_3DClosestPoint(3d, 2d) should be returning a 2d point because
 "distance" (and thus "closeness") is only determined by the 2d component,
 the 3rd being always at distance=0.
