I don't know either, but this brings up another question. Stats wraparound.
We'll all be safely dead, for one thing ;-)

At one update per nanosecond, it'd take approximately 300 years to wrap
a 64-bit counter.  Somehow I don't have a problem with the idea that
Postgres would need to be rebooted that often.  We'd want to fix the
32-bit nature of XIDs long before 64-bit stats counters get to be a
real-world issue ...


*sigh* Sorry, I should have done a little math before I asked that question.....
