I remember hacking that out for testing sake.

I can only justify it as a foot-gun to prevent someone from being
stuck restarting the database to get a reasonable number in there.
Let's CC Peter; maybe he can remember some thoughts about that.

Also, for onlookers, I have changed this patch around to do the
date-oriented stuff but want to look it over before stapling it up and
sending it.  If one cannot wait, one can look at
https://github.com/fdr/postgres/tree/queryid.  The squashed-version of
that history contains a reasonable patch I think, but a re-read often
finds something for me and I've only just completed it yesterday.
