we can't group together multiple varchar values into a IN query, because that forces use to compare varchar values on the vtgate level which we can't do correctly yet Signed-off-by: Andres Taylor <andres@planetscale.com>

We can't bundle together multiple varchar values and query the lookup vindexes using IN queries, because when we do, we then have to be able to compare varchar values at the vtgate level, and that is not always safe.
