        TimescaleDB is a
        time-series database built as a PostgreSQL extension. If enabled, Grafana will use time_bucket in
        the $__timeGroup macro and display TimescaleDB specific aggregate functions in the query builder.
      
      The database user should only be granted SELECT permissions on the specified database & tables you want to query.
      Grafana does not validate that queries are safe so queries can contain any SQL statement. For example, statements
      like DELETE FROM user; and DROP TABLE user; would be executed. To protect against this we
      Highly recommmend you create a specific PostgreSQL user with restricted permissions.
