I never understood why autovacuum should need a particularly short fuse
on the stats file age to start with. If the launcher is launching
multiple workers into the same database with only a few milliseconds
between them, isn't the launcher pretty broken anyhow? ISTM that stats
files even several seconds old ought to be plenty good enough.
