Property::FaultyQuery and FsyncNoWait stored a list of tables to check the on the database. Again, the FaultyQuery could be a Drop Table which meant that we could be running a SELECT on an inexistent table. To solve this, just insert a Property that check all the tables in the db after a Faulty Property

generate extensional queries when iterating over the next interaction, not when generating the property. This is necessary as the extensional queries can modify schema and thus could cause the next queries to fail because the DB enviroment context was not updated on generation time. Rule of thumb: queries should never be generated in bulk, always one a a time so the enviroment can be shadowed accordingly

as we have DROP table now, if we want to generate extensional queries eagerly, without affecting how we document interactions with MVCC, we need to travel forward in time and shadow queries eagerly so we can generate queries correctly. This involves cloning the tables unfortunately which is inneficient but correct

of life upgrade for debugability.
