Configuration for storageClass of result-postgres missing

[MarcusElevait]

Expected Behavior

When installing the components via the helmchart i expect them all to run successfully

Actual Behavior

When installing the chart it has installed the components to tekton-pipelines namespace. Within that namespace the pvc was in pending state, because the storageClass was missing.
I couldn't find any place where to configure this, so what i did is manually editing the pvc and setting the storageClass.

Steps to Reproduce the Problem

1. Install the chart
2. Go to tekton-pipelines namespace pvs
3. Describe the pvc for the result postgres

Additional Info

• Kubernetes version:

  Client Version: v1.32.2
  Kustomize Version: v5.5.0
  Server Version: v1.33.7
  

• Tekton Pipeline version: v1.6.0

We deploy our stuff via flux, so here are the manifests that we used:

---
apiVersion: source.toolkit.fluxcd.io/v1
kind: GitRepository
metadata:
  name: tektoncd-operator
  namespace: tekton
spec:
  interval: 10m
  url: https://github.com/tektoncd/operator
  ref:
    tag: v0.78.1
---
apiVersion: source.toolkit.fluxcd.io/v1
kind: HelmChart
metadata:
  name: tekton-operator
  namespace: tekton
spec:
  interval: 10m
  chart: charts/tekton-operator
  sourceRef:
    kind: GitRepository
    name: tektoncd-operator

@pratap0007 Can you have a look ?

I ran into the same issue as well.
It seems that manual operation is inevitable, the default PVC size is only 1GB, and this setting can only be modified manually after the Tekton server instance deployed — it cannot be changed during the deployment process.

According to the official documentation, an external PostgreSQL database should be specified for production environments. However, these configurations currently cannot be provided or customized when deploying the Helm chart.
