I see two problems with this report:
1. it creates a new installation for each run,
2. it only uses the serial schedule.

I care more about the parallel schedule than the serial one, because
since it obviously runs in less time, then I can run it often and not
worry about how long it takes.  On the other hand, the cost of the extra
initdb obviously means that the percentage is a bit lower than if you
were to compare test run time without considering the initdb step.
