-------------------------------------------------------------------------

Current solution:
- Materialized views are materialized without taking into account policies 
defined on source tables.
- If a user queries the source tables used by a materialized view, the policies 
are applied as usual (if defined). This may result in triggering a rewriting 
using a materialized view but filtering/masking after reading contents from the 
materialized view.
- Policies on a materialized view cannot be defined and will not be enforced.
- For any given user, if a materialized view uses source tables that are 
masked/filtered through policies, then the user cannot query the materialized 
view directly (e.g., {{SELECT * FROM mv}}). We throw an error.
