Installing a pgautofailover Systemd unit

The command pg_autoctl show systemd outputs a systemd unit file that you can use to setup a boot-time registered service for pg_auto_failover on your machine.

Here’s a sample output from the command:

Copy/pasting the commands given in the hint output from the command will enable the pgautofailer service on your system, when using systemd.

It is important that PostgreSQL is started by pg_autoctl rather than by systemd itself, as it might be that a failover has been done during a reboot, for instance, and that once the reboot complete we want the local Postgres to re-join as a secondary node where it used to be a primary node.
