The version that I committed had the following change to
002_pg_upgrade.pl:

  # Stabilize stats before pg_dumpall.
  $oldnode->append_conf('postgresql.conf', 'autovacuum = off');
  $oldnode->restart;

  ...

  $newnode->append_conf('postgresql.conf', 'autovacuum = off');

I think we need a similar change in the buildfarm client's
TestUpgradeXversion.pm? Is -hackers the right place to discuss that?
