Postgres has no auto-failover. You would have to build that functionality
yourself. Just make sure that (if you're actually going to automate it,
which I don't usually recommend) your scripts are very pessimistic about
failing over.

The trigger file is something that you would have to create either manually
or (again, not recommended) programatically.
