The only possible doc change I think warranted is to tell people NOT to use
pg_ctl with systemd (because it makes no sense), but just use the binary
instead. However, the example in the docs (
https://www.postgresql.org/docs/current/server-start.html) already does
that, ,and works fine as written, so I don't think the docs should
anticipate every way in which someone might wrongly modify the file.
Cheers,
Greg
