The contents of the trigger file are irrelevant, it is just a switch: the existence of the file tells the standby to stop recovering. To automate failover, you need some cluster software. It is a nontrivial problem to detect if the primary really went down. You can't have the standby make this decision by itself -- it could be that it is the standby that has a problem that keeps it from seeing the primary. Moreover, you should have a way to deactivate the old primary when you fail over, otherwise you might end up with two servers who both think that they are the active one.
