This part of the documentation is really aimed at being short. Please
note as well that this has been added to the documentation of Postgres
10 with this commit:
commit: fbe7a3fa45f360e73ce141e51005a3e86cd1926c
author: Peter Eisentraut <peter_e@gmx.net>
date: Wed, 15 Feb 2017 10:46:31 -0500
doc: Add advice about systemd RemoveIPC

Reviewed-by: Magnus Hagander <magnus@hagander.net>

Here is the link to it:
https://www.postgresql.org/docs/devel/static/kernel-resources.html#systemd-removeipc
And the important quote:
"Packaging and deployment scripts should be careful to create the
postgres user as a system user by using useradd -r, adduser --system,
or equivalent."
