Whenever someone actually writes a pg_upgrade, we'll institute a policy
to restrict changes it can't handle. But until we have a credible
upgrade tool it's pointless to make any such restriction. ("Credible"
means "able to handle system catalog restructurings", IMHO --- without
that, you'd not have any improvement over the current rules for minor
releases.)
