Version 2.x of the postgresql-backupscript package switched from 
cron to systemd-timer to start the backup. This allows a better 
fine tuning, when the script should be executed.

If you migrate from Version 1.x of the script to version 2.x, please 
activate the backup via:

 systemctl enable postgresql-backupscript.timer

You can also savely remove any left over files in /etc/cron.daily/ -
usually this can be done via: 
 rm /etc/cron.daily/suse.de-postgresql-backup.rpmsave
as root (in case you changed something in the script).
