Description

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.
