This is a preparatory change that allows connectors to store information about the WHEN STALE behavior. The option cannot yet be used in practice, as execution will still fail with a NOT_SUPPORTED error.
Behavior: - `FAIL` - If the MV is stale, queries referencing it will fail. Analysis of the underlying query is never performed while querying the MV. - `INLINE` - Preserves the current behavior. Even if the MV is stale, it is expanded like a logical view, and the underlying query is analyzed. Motivation: - Avoid analyzing the underlying query every time, which can be costly when it references many tables. - Allow using fresh MVs even when some data sources are temporarily unavailable.

I believe that in this case we should query the base tables, because we use a session (futureSession) that started after the grace period expired.
