Review Comment:
   This is not consistent with the following coercion rules used for columns 
(see `AbstractTypeCoercion::commonTypeForBinaryComparison`):
   
   > // 1 > '1' will be coerced to 1 > 1.
       if (SqlTypeUtil.isAtomic(type1) && SqlTypeUtil.isCharacter(type2)) 
          return type1;
   
   >   if (SqlTypeUtil.isAtomic(type2) && SqlTypeUtil.isCharacter(type1)) 
          return type2
   
   I think this if-clause is unnecessary.
