Postgres runs under other user/group, update crashs installation

 
Hey Folks,
we use postgres from the actual RHEL 7 repo.I installed it some weeks ago and changed the user/group under which the service
runs via systemd:userdel postgresgroupdel postgreschown newuser.newgroup /var/run/postgresql -Rchown newuser.newgroup /var/lib/pgsql -R systemctl edit postgresql.servicecontent:[Service]User=newuserGroup=newgroupThis works like a charm, until i updated to 9-2-18 yesterday.In the back to postgres.postgres. Which lead to a postgres instance which couldnt start anymore because "newuser" can access the files....How can i configure postgres so it doesnt break while updating?Thanks a lot!
