I've run the regression tests several times (also the parallel ones and
bigtest). It failed geometry, but it always does due to different
rounding. Passed everything else, so it looks ok.

Now I'm trying to figure out how I can do a sensible timing test on the
two versions to see whether it is any faster. The postgres benchmark
finishes in such a ridiculously short time, that that isn't telling me
anything.
