Just to be clear, I'm entirely *not* on board with that. IMV it's
intentional that we do not force auto-analyze activity after CREATE
INDEX or CREATE STATISTICS. If we change that, people will want a
way to opt out of it, and then your "simple" patch isn't so simple
anymore. (Not that it was simple anyway. What if the CREATE is
inside a transaction block, for instance? There's no use in
kicking autovacuum before commit.)
