I think if the linux user is defined as a system user, then you are OK.  It's only when the user is not defined as a system user that these bad side-effects can happen.
 
When creating linux users that work with Postgres, do it like this:
adduser -r myuser
or
useradd -m --system myuser
 
See "systemd RemoveIPC" section in 
https://www.postgresql.org/docs/current/kernel-resources.html

Context is in parallel workers. Does this just mean that I don't have enough shmem allocated for the PG config that I set up?
If you are using a Systemd-enabled Linux, check that "RemoveIPC" is
set to "no".
 
See: https://wiki.postgresql.org/wiki/Systemd
