Yes, it is running as postgres user. Looking at postgresql95-setup I can
see that the only reason it is running 'systemctl' is to determine the
PGDATA path, as follows:

PGDATA=`systemctl show -p Environment "${SERVICE_NAME}.service" |
                   sed 's/^Environment=//' | tr ' ' '\n' |
                   sed -n 's/^PGDATA=//p' | tail -n 1`
if [ x"$PGDATA" = x ]; then
       echo "failed to find PGDATA setting in ${SERVICE_NAME}.service"
       exit 1
fi


Further down it gets PGDATA again as follows:

# Get data directory from the service file
PGDATA=`sed -n 's/Environment=PGDATA=//p' "${SERVICE_FILE}"`


When I comment out the first method, PGDATA is set from second method
and the script runs successfully *without* needing root privileges. Is
the first method even necessary!?
