"/var/lib/postgresql/data/pgdata/pg14" has invalid permissions

After installing harbor via helm with below "harbor-values.yml" on kubernetes cluster it crashes after a while:

First harbor-database-0 then harbor-core and harbor-jobservice end up in CrashLoopBackOff due to permissions error:

Error from "kubectl logs pod/harbor-database-0 -n harbor":

Defaulted container "database" out of: database, data-migrator (init), data-permissions-ensurer (init)

2024-04-22 13:45:37.101 UTC [1] DETAIL:  Permissions should be u=rwx (0700) or u=rwx,g=rx (0750).

we are using following helm-values.yml

expose:
  type: ingress
  ingress:
    annotations:
      kubernetes.io/tls-acme: "true"
    hosts:
      core: harbor.dev.test.de
  tls:
    enabled: true
    certSource: auto

Does anyone have a clue what could cause this?
