TYPO3 DB caching tables should not be removed by DB compare
To add robustness and easy recoverability from temporary system failures, planned downtimes or configuration errors, I think the basic Caching DB tables (cf_cache_pages etc.) for the Database Backend should never be removed. That way it would be easier to switch back to Database Caching Backend without having to do a DB compare again.
Currently, the DB compare suggests to remove these tables (if something other than the default DB backend is configured). I never do that but an overzealous admin might.

thanks for creating this issue. however I still would like to close this for the following reasons: The tables are never removed automatically but need interaction by an admin/system maintainer. The configuration of caching strategy can only done by file access which means it requires a developer. Both types of persons must know the impact of reconfiguration and db compare.
furthermore the tables can already stay in the DB even if you use a different caching strategy.
