+Extending PostgreSQL image by enabling extension
+================================================
+
+This is an example how to use the feature of extending the image (see more at https://github.com/sclorg/postgresql-container/tree/generated/12#extending-image) to enable extension `pg_stat_statements`.
+
+To use this in a Dockerfile, run:
+
+```
+podman build . -t my_postgresql:12
+```
+
+Then, run the resulting image as usually:
+
+```
+podman run -d -e POSTGRESQL_ADMIN_PASSWORD=password my_postgresql:12
+```
+
+And see the extension is enabled:
+```
+podman exec -ti -l bash
+bash-4.4$ psql
+psql (12.1)
+Type "help" for help.
+
