Well, the more general point is what should "SHOW session_authorization"
show in an autovacuum process? The fact that Andrew wasn't
intentionally doing that doesn't mean that someone else might not try
it. I think we can either decide it should be an obviously-illegal
value, or try to make it return the name of the cluster-creating
superuser. The latter seems like more work than it's worth though.
