https://github.com/doctrine/dbal/pull/6179 (based on refactoring from https://github.com/doctrine/dbal/pull/3836) deprecates methods from the Doctrine DBAL's query builder that allows fetching and resetting the query parts, which the single table adapter uses to function. This adapter's functionality will need to be re-evaluated to determine if it can be implemented without the features removed from DBAL 4.0 or it'll need to be deprecated/removed.
