+
+[pg_qualstats](https://github.com/powa-team/pg_qualstats) is a PostgreSQL
+extension that collects statistics about predicates (quals) found in
+`WHERE` clauses and `JOIN` conditions. It can be used to identify missing
+indexes and understand query workload patterns. For more information, see the
+[official documentation](https://powa.readthedocs.io/en/latest/components/pg_qualstats.html).
+
+## Usage
+
+The `pg_qualstats` extension must be loaded via `shared_preload_libraries`
+to hook into the query executor and collect predicate statistics.
+
+### 1. Add the pg_qualstats extension image to your Cluster
+
+Define the `pg-qualstats` extension under the `postgresql.extensions` section
+of your `Cluster` resource. For example:
+
+```yaml
+apiVersion: postgresql.cnpg.io/v1
+kind: Cluster
+metadata:
+  name: cluster-pg-qualstats
+spec:
+  imageName: ghcr.io/cloudnative-pg/postgresql:18-minimal-trixie
+  instances: 1
+
+  storage:
+    size: 1Gi
+
+  postgresql:
+    shared_preload_libraries:
+    - pg_qualstats
+    extensions:
+    - name: pg-qualstats
+      image:
+        # renovate: suite=trixie-pgdg depName=postgresql-18-pg-qualstats
+        reference: ghcr.io/cloudnative-pg/pg-qualstats:2.1.3-18-trixie
+```
+
+### 2. Enable the extension in a database
+
+You can install `pg_qualstats` in a specific database by creating or updating a
+`Database` resource. For example, to enable it in the `app` database:
+
+```yaml
+apiVersion: postgresql.cnpg.io/v1
+kind: Database
+metadata:
+  name: cluster-pg-qualstats-app
+spec:
+  name: app
+  owner: app
+  cluster:
+    name: cluster-pg-qualstats
+  extensions:
+  - name: pg_qualstats
+    # renovate: suite=trixie-pgdg depName=postgresql-18-pg-qualstats
+    version: '2.1.3'
+```
+
+### 3. Verify installation
+
+Once the database is ready, connect to it with `psql` and run:
+
+```sql
+\dx
+```
+
+You should see `pg_qualstats` listed among the installed extensions.
