rewriting is LGTM.

My question is: The PR retains three types

• TableType::Table
• TableType::MaterializedView
• TableType::Index

This is not consistent with the previous implementation (which only kept MaterializedView), is this as expected? Can you add some pr description.

Only user-queryable state tables are included in the time travel metadata, both for previous implementation and current one.
