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 that they suggest something's seriously wrong. regards, tom lane
