+# pg_jsonschema
+
+[pg_jsonschema](https://github.com/supabase/pg_jsonschema) is a PostgreSQL
+extension that adds JSON Schema validation for `json` and `jsonb` data.
+
+This image provides a convenient way to deploy and manage `pg_jsonschema` with
+[CloudNativePG](https://cloudnative-pg.io/).
+
+## Usage
+
+### 1. Add the extension image to your Cluster
+
+Define the `pg-jsonschema` extension under the `postgresql.extensions` section
+of your `Cluster` resource. For example:
+
+```yaml
+apiVersion: postgresql.cnpg.io/v1
+kind: Cluster
+metadata:
+  name: cluster-pg-jsonschema
+spec:
+  imageName: ghcr.io/cloudnative-pg/postgresql:18-minimal-trixie
+  instances: 1
+
+  storage:
+    size: 1Gi
+
+  postgresql:
+    extensions:
+    - name: pg-jsonschema
+      image:
+        # renovate: datasource=github-tags depName=supabase/pg_jsonschema versioning=semver extractVersion=^v(?<version>.*)$
+        reference: ghcr.io/cloudnative-pg/pg-jsonschema:0.3.4-18-trixie
+```
+
+### 2. Enable the extension in a database
+
+Create or update a `Database` resource to install the extension in a specific
+database:
+
+```yaml
+apiVersion: postgresql.cnpg.io/v1
+kind: Database
+metadata:
+  name: cluster-pg-jsonschema-app
+spec:
+  name: app
+  owner: app
+  cluster:
+    name: cluster-pg-jsonschema
+  extensions:
+  - name: pg_jsonschema
+    # renovate: datasource=github-tags depName=supabase/pg_jsonschema versioning=semver extractVersion=^v(?<version>.*)$
+    version: "0.3.4"
+```
+
+### 3. Verify installation
+
+Once the database is ready, connect to it with `psql` and run:
+
+```sql
+\dx
+```
+
+You should see `pg_jsonschema` listed among the installed extensions.
