need to add a check for the integrity of base CDC table besides the check for the result of query q4, so we can know if the problem lies in the CDC or the query itself

Why we only check the checksum of q4? I remembered we also checked source tables before. Please add check for source tables and reproduce the issue again. cc @cyliu0
