There are a couple of issues that need fixing:
1) "backoffLimit" and "activeDeadlineSeconds" attributes are placed in
the CronJob part of the cron-job-backup-postgres.yaml, but should be
placed in the Job template part.
2) The backup cronjob had two names in the values.yaml
"backup_postgresql" and "postgresql_backup" in various places. It should
be "postgresql_backup" in all of those places so that the CronJob can be
deployed correctly.
