Hi! thank you for this great operator.
I installed postgres-operator with option and all work fine.

configKubernetes:
  cluster_labels:
    app.kubernetes.io/name: db-postgres

But when I set up logical backups and a CronJob is created, it does not inherit the necessary labels along the way - spec/jobTemplate/spec/template/metadata/labels
Only default values (cluster-name and application) without app.kubernetes.io/name: db-postgres:

apiVersion: batch/v1
kind: CronJob
metadata:
  labels:
    app.kubernetes.io/name: db-postgres
    application: spilo
    cluster-name: my-cluster
    team: dba
spec:
  jobTemplate:
    spec:
      template:
        metadata:
          labels:
            application: spilo-logical-backup
            cluster-name: my-cluster

Indeed, we only set cluster name and application label for job template. Should be easy to fix by using c.labelsSet(true) and then exchanging the application from spilo to spilo-logical-backup.
