TAJO-1933: When a simple query executed on partitioned tables, the number
of result rows is always the number of rows of the whole table
I've changed to print unknown row number and unknown bytes if the total row
number is larger than that printed in a page. Otherwise, the actual row number
is printed.
IMHO, this is valid because the execution of a simple query is an iterable
process, so it is difficult to get the total row number of the result.
