I've committed the core of this. I left out the stats collector
stuff, because it's still per-table and I think perhaps we should back
off to just per-database. I changed it so that it does not conflate
wait time with I/O time. Maybe there should be a separate method of
measuring wait time, but I don't think it's a good idea for the
per-backend stats to measure a different thing than what gets reported
up to the stats collector - we should have ONE definition of each
counter. I also tweaked the EXPLAIN output format a bit, and the
docs.
