 # Postgres
 
-Short Term Rental Data Sharing System (STRDSS) is using bitnami/postgresql with chart version 15.5.20
+The Short Term Rental Data Sharing System (STRDSS) utilizes the bitnami/postgresql Helm chart, version 15.5.38.
+
+However, the network policy for the database is not managed by the Helm chart and must be created manually. This is due to the following configuration:
+
+```yaml
+  networkPolicy:
+    enabled: false
+```
+
+Instead, the network policies for the database are created through the application Helm chart maintained in the application's GitOps repository. These policies include:
+
+* [Allow ingress from backend](https://github.com/bcgov-c/tenant-gitops-b0471a/blob/07f42166586b9a9d986045a027bb0f0fa0b4981f/charts/backend/templates/backend-networkpolicy.yaml#L126).
+* [Allow ingress from hangfire](https://github.com/bcgov-c/tenant-gitops-b0471a/blob/07f42166586b9a9d986045a027bb0f0fa0b4981f/charts/hangfire/templates/hangfire-networkpolicy.yaml#L74).
