In order to maintain data privacy in production environments, while also supporting a production-like configuration for testing and troubleshooting - it would be helpful to have support for the PostgreSQL Anonymizer extension.

The ideal workflow would be to create a follower of our production database which would house a restored backup of production, but with anonymization rules applied via this extension.

Once in place data integrity on production can be better protected by limiting developer access to the anonymized lesser environments.
