repmgr.service

Please modify the repmgr-9.x.service files for the packages.

The service files currently have:

ExecStop=/usr/bin/kill -TERM ${PIDFILE}
> ExecReload=/usr/bin/kill -HUP ${PIDFILE}

/bin/kill does not accept files, you may be thinking of /bin/pkill -f

Replace them with:

ExecStop=/usr/bin/kill -TERM $MAINPID
> ExecReload=/usr/bin/kill -HUP $MAINPID

$MAINPID is a special systemd provided variable that references the known
PID of the process

And add the following under the [Service] section:

PIDFile=/var/run/repmgr/repmgrd-9.x.pid

This prevents systemd from guessing what the PID is and being wrong when
Type=forking

As it stands now `systemctl stop repmgrd` and `systemctl reload repmgrd`
will always fail.
