74-271: Common RBAC rules are appropriately defined

The cloudnative-pg.commonRules function defines a comprehensive set of RBAC rules for namespace-scoped operations. The resources and verbs specified align well with the operator's requirements.

---

276-301: Cluster-wide RBAC rules are appropriately defined

The cloudnative-pg.clusterwideRules function specifies necessary cluster-wide permissions, including access to nodes and webhook configurations, which are essential for the operator's cluster-wide functionalities.

packages/system/postgres-operator/charts/cloudnative-pg/templates/monitoring-configmap.yaml (1)

21-21: Namespace inclusion in ConfigMap metadata is correctly implemented

Adding namespace: {{ include "cloudnative-pg.namespace" . }} ensures the ConfigMap is deployed in the correct namespace, especially when namespaceOverride is used.

packages/system/postgres-operator/charts/cloudnative-pg/templates/service.yaml (1)

21-21: LGTM! Enhanced service configuration capabilities.

The changes appropriately add namespace configuration and flexible IP family settings, improving the service's networking capabilities.

Also applies to: 30-36, 50-56

✅ Verification successful

✅ Configuration merge behavior verified and correct

The implementation correctly handles both cluster-wide and namespace-scoped configurations:

• Preserves existing configuration when merging WATCH_NAMESPACE
• Consistently applies namespace restrictions across config and deployment
• Properly documented in values.yaml with multi-namespace support

packages/system/postgres-operator/charts/cloudnative-pg/templates/rbac.yaml (1)

22-22: LGTM! Enhanced RBAC configuration with proper scope separation.

The changes correctly implement:

1. Proper RBAC separation for cluster-wide vs namespace-scoped deployments
2. Addition of new resources to view/edit roles
3. Appropriate namespace-specific role bindings

Also applies to: 44-51, 71-112, 131-135, 157-161

✅ Verification successful

RBAC changes verified - proper implementation of namespace scoping and resource access

The changes correctly implement:

1. Proper namespace scoping through template variables
2. Separation of cluster-wide vs namespace-scoped permissions
3. Least-privilege access for new resources (databases, publications, subscriptions)
4. Correct RBAC aggregation for admin/edit/view roles

2. Concurrent reconciliation control
3. Proper namespace scoping

Also applies to: 36-38, 62-62, 85-88

✅ Verification successful

Configuration parameters are properly implemented and aligned with operator patterns

The max-concurrent-reconciles value of 10 and namespace-scoped watching are consistent with other operators in the system, following established patterns for Kubernetes operators.

• Chart version: 0.22.0 → 0.23.0
• App version: 1.24.0 → 1.25.0

---

33-36: New configuration options enhance operator flexibility.

The new configuration options provide better control over the operator's behavior:

72-73: Verify dual-stack configuration documentation.

The documentation for dual-stack configuration should include examples of valid values for ipFamilies and ipFamilyPolicy.

Consider adding examples like:

 | service.ipFamilyPolicy | string | `""` | Set the ip family policy to configure dual-stack see [Configure dual-stack](https://kubernetes.io/docs/concepts/services-networking/dual-stack/#services) |
+| | | | Example values: SingleStack, PreferDualStack, RequireDualStack |
 | service.ipFamilies | list | `[]` | Sets the families that should be supported and the order in which they should be applied to ClusterIP as well. Can be IPv4 and/or IPv6. |
+| | | | Example values: ["IPv4"], ["IPv6"], ["IPv4", "IPv6"], ["IPv6", "IPv4"] |

✅ Verification successful

Documentation examples would improve clarity and usability

The suggested examples are accurate and would be valuable additions to the documentation. The values match the Kubernetes implementation as verified in the CRDs, and currently, there are no examples in the documentation to guide users.
