Fix ranged load from MySQL does not load the last record.

[lukesilvia]

Problem

I tried to load MySQL tables into PostgreSQL with rows per range option. The following is full with options.

WITH workers = 8, concurrency = 2, multiple readers per thread, rows per range = 50000, batch rows = 10000, prefetch rows = 10000

But at some tables, the last record was not copied to PostgreSQL.

Cause

where clause for ranged load seems to ignore the last record (or the record has max primary key).

(let ((sql (format nil "~a WHERE `~a` >= ~a AND `~a` < ~a"

Thank you for checking my pull request.
