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

See the updated output for create_view.q.out for an example of what we'll be storing in the
view descriptor after this change.

> Zheng's description:
> 5. TODO: Metadata change: We store "view" definitions in the same metadata table that
we store "table" definitions.
> Shall we add a field "table type" so we know whether it's a table, external table, view,
or materialized view in the future.
> We should clean up the additional useless fields in "view" - the test output shows that
we are storing some garbage information for views.
