+# pg\_partman
+
+[pg\_partman](https://github.com/pgpartman/pg_partman) is an open-source extension
+that enables **automatic partition management** in PostgreSQL.
+
+This image provides a convenient way to deploy and manage `pg_partman` with
+[CloudNativePG](https://cloudnative-pg.io/).
+
+## Usage
+
+### 1. Add the pg\_partman extension image to your Cluster
+
+Define the `pg_partman` extension under the `postgresql.extensions` section of
+your `Cluster` resource. For example:
+
+```yaml
+apiVersion: postgresql.cnpg.io/v1
+kind: Cluster
+metadata:
+  name: cluster-pgvector
+spec:
+  imageName: ghcr.io/cloudnative-pg/postgresql:18-minimal-trixie
+  instances: 1
+
+  storage:
+    size: 1Gi
+
+  postgresql:
+    extensions:
+    - name: pg_partman
+      image:
+        reference: ghcr.io/cloudnative-pg/pg_partman:5.3.1-2-trixie
+```
+
+### 2. Enable the extension in a database
+
+You can install `pg_partman` 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_partman-app
+spec:
+  name: app
+  owner: app
+  cluster:
+    name: cluster-pg_partman
+  extensions:
+  - name: pg_partman
+```
+
+### 3. Verify installation
+
+Once the database is ready, connect to it with `psql` and run:
+
+```sql
+\dx
+```
+
+You should see `pg_partman` listed among the installed extensions.
