'''Note on error emails during upgrade:''' Background workers from previous deployments may still be running when the upgrade restarts PostgreSQL. These workers will lose their database connection and crash, triggering error alert emails. This is expected behaviour and not a sign of anything wrong. One way to avoid this is to explicitly stop all Zulip services before running the upgrade script.
