Instead of the above, I ended up modifying the two intermittently
failing tests to change the ANALYZE into a VACUUM ANALYZE. This
should prevent autovacuum sneaking in a vacuum at some point in time
after the ANALYZE has taken place.
I don't believe any of the current buildfarm failures can be
attributed to any of the recent changes to autovacuum, but I'll
continue to monitor the farm to see if anything is suspect.
