      Initial sync will drop all tables in all replicated databases without a timestamp before resyncing. This means that the drop pending ident reaper will immediately drop the table in WT the next time it runs. The table drops in WT are non-transactional and cannot be rolled back. This leads to immediately dropping the table in WT even if the catalog changes are not stable/checkpointed. As a result, during startup recovery, the table no longer exists in WT but continues to exist in the catalog. The server tries to query the index table metadata from WT but WT likely returns ENOENT and we crash.
