Very interesting stuff! Is it possible to see a history of a column, table, schema, etc? Is it possible to tag a certain point in time? It would be liberating

Very interesting stuff! Is it possible to see a history of a column, table, schema, etc? Is it possible to tag a certain point in time? It would be liberating for many schema designs that we could just change stuff and be sure that the database knew what was changed and when with the ability to roll changes back.
