PG HA docs flow, completed -> troubleshooting
The flow of the main section is a little jarring. It goes Required Information -> Configuration per role -> Manual steps per role -> Alternative configurations -> Troubleshooting
I think Troubleshooting belongs after 'Manual steps per role', probably structurally, or if not with a link at the end of the last manual step to say "you should be done now, if not #Troubleshooting"
