+
+<!--
+TODO: Replace this section with a brief introduction of your extension.
+Describe what the extension does and what it is useful for.
+Add a reference to the official documentation if available.
+-->
+
+The pg_repack PostgreSQL extension provides a binary tool that can perform online operation that can remove bloat from tables and indexes. For more information, see the [official documentation](https://reorg.github.io/pg_repack/).
+
+## Usage
+
+<!--
+Usage: add instructions on how to use the extension with CloudNativePG.
+Include code snippets for Cluster and Database resources as needed.
+-->
+
+### 1. Add the pg_repack extension image to your Cluster
+
+Define the `pg_repack` extension under the `postgresql.extensions` section of
+your `Cluster` resource. For example:
+
+```yaml
+apiVersion: postgresql.cnpg.io/v1
+kind: Cluster
+metadata:
+  name: cluster-pg_repack
+spec:
+  imageName: ghcr.io/cloudnative-pg/postgresql:18-minimal-trixie
+  instances: 1
+
+  storage:
+    size: 1Gi
+
+  postgresql:
+    extensions:
+    - name: pg_repack
+      image:
+        # renovate: suite=trixie-pgdg depName=postgresql-18-pg_repack
+        reference: ghcr.io/cloudnative-pg/pg_repack:1.0-18-trixie
+```
+
+### 2. Enable the extension in a database
+
+You can install `pg_repack` 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_repack-app
+spec:
+  name: app
+  owner: app
+  cluster:
+    name: cluster-pg_repack
+  extensions:
+  - name: pg_repack
+    # renovate: suite=trixie-pgdg depName=postgresql-18-pg_repack extractVersion=^(?<version>\d+\.\d+\.\d+)
+    version: '1.0'
+```
+
+<!--
+TODO: Adjust the extractVersion regex pattern above based on your extension's versioning scheme
+Examples: \d+\.\d+ for major.minor (e.g., "18.0"), \d+\.\d+\.\d+ for major.minor.patch (e.g., "0.8.2")
+-->
+
+### 3. Verify installation
+
+Once the database is ready, connect to it with `psql` and run:
+
+```sql
+\dx
+```
+
+You should see `pg_repack` listed among the installed extensions.
