+# PostgreSQL Anonymizer
+<!--
+SPDX-FileCopyrightText: Copyright © contributors to CloudNativePG, established as CloudNativePG a Series of LF Projects, LLC.
+SPDX-License-Identifier: Apache-2.0
+-->
+
+The [PostgreSQL Anonymizer](https://gitlab.com/dalibo/postgresql_anonymizer) (or
+`anon`) is an extension to mask or replace [personally identifiable information] (PII) or
+commercially sensitive data from a Postgres database. For more information, see the [official documentation](https://postgresql-anonymizer.readthedocs.io).
+
+## Usage
+
+### 1. Add the PostgreSQL Anonymizer extension image to your Cluster
+
+Define the PostgreSQL Anonymizer extension `anon` under the
+`postgresql.extensions` section of your `Cluster` resource.
+
+For example:
+
+```yaml
+apiVersion: postgresql.cnpg.io/v1
+kind: Cluster
+metadata:
+  name: cluster-postgresql-anonymizer
+spec:
+  imageName: ghcr.io/cloudnative-pg/postgresql:18-minimal-trixie
+  instances: 1
+
+  storage:
+    size: 1Gi
+
+  postgresql:
+    extensions:
+    - name: anon
+      image:
+        # renovate: suite=trixie-pgdg depName=postgresql-18-postgresql-anonymizer
+        reference: ghcr.io/cloudnative-pg/postgresql_anonymizer:3.2.2-18-trixie
+```
+
+### 2. Enable the extension in a database
+
+You can install PostgreSQL Anonymizer extension `anon` in a specific database by
+creating or updating a `Database` resource. For example, to enable it in a
+`db` database:
+
+```yaml
+apiVersion: postgresql.cnpg.io/v1
+kind: Database
+metadata:
+  name: database-postgresql-anonymizer
+spec:
+  name: db
+  owner: app
+  cluster:
+    name: cluster-postgresql-anonymizer
+  extensions:
+  - name: anon
+  # renovate: suite=trixie-pgdg depName=postgresql-18-postgresql-anonymizer extractVersion=^(?<version>\d+\.\d+\.\d+)
+    version: '3.2.2'
+```
+
+On top of the creation, it's recommended to load the extension in the `db` database.
+This can be done with this command :
+
+```sql
+ALTER DATABASE db SET session_preload_libraries = 'anon';
+```
+
+The setting will be applied for the next sessions.
+You need to reconnect to the database for the change to visible.
+
+### 3. Initialize the extension
+
+After reconnection, you can initialize the extension with the `anon.init()` function :
+
+```sql
+db=# SELECT anon.init('/extensions/anon/share/extension/');
+ init 
+------
+ t
+(1 row)
+```
+
+### 4. Verify installation
+
+Once the `db` database is ready, connect to it with `psql -d db` and run :
+
+```sql
+SELECT * FROM pg_extension WHERE extname = 'anon';
+```
+
+```sql
+db=# SELECT * FROM pg_extension WHERE extname = 'anon';
+  oid  | extname | extowner | extnamespace | extrelocatable | extversion | extconfig | extcondition 
+-------+---------+----------+--------------+----------------+------------+-----------+--------------
+ 16394 | anon    |       10 |         2200 | f              | 3.2.2      |           | 
+(1 row)
+```
+
+If the result is empty, the extension is not declared in your database.
+
+Finally, look at the state of the extension with :
+
+```sql
+SELECT anon.is_initialized();
+```
+
+```console
+db=# SELECT anon.is_initialized();
+ is_initialized 
+----------------
+ t
+(1 row)
+```
+
+If the result is not `t`, the extension's data is not present.
