MDEV-22583: Selectivity for BIT columns in filtered column for EXPLAI…
…N is incorrect For BIT columns when EITS is collected, we store the integral value in text representation in the min and max fields of the statistical table When this value is retrieved from the statistical table to original table field then we try to store the text representation in the original field which is INCORRECT. The value that is retrieved should be converted to integral type and that value should be stored back in the original field. This would get us the correct estimate for selectivity of the predicate.
