Hello,

I see in the workload manager that there's an option to inject a postgres DB URL.

I personally use CNPG to manage application databases: https://github.com/cloudnative-pg/charts

This chart/operator spins up a DB/cluster, pvc, replicas, etc AND has init container/configs that allow me to auto-generate user accounts + passwords, writing those secrets to a namespace.

I'm wondering -- are there any plans on supporting k8s secrets in the db config for this chart? I'm not too familiar with the open-webui container env-vars and am wondering if instead of using DATABASE_URL if it is, or would eventually be, possible to do something like this instead:

# somewhere in workload-manager.yaml
spec:
    template:
        metadata:
            spec:
            # ...
            containers:
            # ...
            - name: {{ .Chart.Name }}
              # ...
              env:
                - name: DATABASE_USER
                   valueFrom:
                     secretKeyRef:
                       name: {{ .Values.postgres.auth.secret.name }}
                       key: {{ .Values.postgres.auth.secret.userKey }}
                - name: DATABASE_PASSWORD
                     secretKeyRef:
                       name: {{ .Values.postgres.auth.secret.name }}
                       key: {{ .Values.postgres.auth.secret.passwordKey }}
                - name: DATABASE_URL
                   value: my-cnpg-db-cluster-svc.openwebui.svc.cluster.local
                - name: DATABASE_PORT
                   value: 5432

Hey @chr0n1x, the best way to do this currently would be using extraEnvFrom (https://github.com/open-webui/helm-charts/blob/main/charts/open-webui/values.yaml#L366), which allows you to set values to existing secrets.
