> VerifyReplicaiton could compare the source table with its peer table and compute BADROWS.
However, the current BADROWS computing method might not be accurate enough. For example, if
source table contains rows as {r1, r2, r3, r4} and peer table contains rows as {r1, r3, r4},
the BADROWS counter will be 3 because 'r2' in source table will make all the later comparisons
fail. Will it be better if the BADROWS is computed to 1 in this situation? Maybe, we can compute
the BADROWS more accurately in merge comparison?
