Grafana does not validate that queries are safe so queries can contain any SQL statement. For example, statements like <code>DELETE FROM user;</code> and <code>DROP TABLE user;</code> would be executed. To protect against this we <strong>Highly</strong> recommmend you create a specific PostgreSQL user with restricted permissions. </p> </div> </div>
