Review comment:
I get it that we want to keep the diff small so we leave the indentation
wrong here, but we can avoid this problem completely.
An empty batch has nearly 0 overhead. The `RuleExecutor` just runs an empty
loop and goes to the next batch. The join-reorder optimization can be turned
off and we still keep its batch.
