From: Joseph Kogut <joseph.kogut at gmail.com>
During activation, pg_ctl uses exec to start the db server, which causes
the service to never finish activating when Type=forking. Upstream
recommends configuring --with-systemd and using Type=notify.
https://www.postgresql.org/docs/10/static/server-start.html
Upstream says:
When using systemd, you can use the following service unit file
[...]
Using Type=notify requires that the server binary was built with
configure --with-systemd.
