Can I take a small downtime and stop all applications and switchover or shall I simply switchover during low traffic time?

In my experience:
- Patroni switchover happens in a few seconds
- If you use pgbouncer, the client connections don't get dropped. A client that issues a query in that brief window will get an error.
- If your clients have retry logic, your users will never notice the failover.
