Yes. The unit file is already stripped down: it does nothing except
"pg_ctl start". The init script had accumulated a whole lot of
perhaps-unnecessary sanity-checking, which frankly I'd rather have kept
but the systemd mantra seems to be "no shell scripting" so I didn't.
Michal's numbers look pretty damning, and I find it remarkable that the
systemd advocates seem to have managed not to read them, let alone admit
