Comment (by nicklas):

 I think I can explain this difference. In my functions I always calculate
 a point along an edge, because it's needed in st_shortestline and then I
 push that point to the point-point distance calculation just the same way
 as if it would have been two vertexes. Before the distance was calculated
 to the edge without identyfying the point. Because of that there is a
 round at the last decimal to store the point and I guess that's why it
 differs there.

 About the issue I mentioned earlier it seems to be fixable, but it will
 take a day or two before I have time for it.
