Also check that result is the same for ```sql SELECT '2020-01-01 00:00:00.000' AS a, '2020-01-01 00:00:00.000001' AS b, b > a AS str, toDateTime64(b, 6) > toDateTime64(a, 3) AS datetime64,...

I wonder why this does not throw an error (it cannot / should not use index, but it does not erroring) ```sql drop table dt64_monot_test_string; create table dt64_monot_test_string(date_time String, x...

`toDateTime64()` should not be monotonic and this query does a table fullscan, thus `force_index_by_date=1, force_primary_key=1;` should throw an error.

@orloffv it's not the same, they are not related. This PR makes `toDateTime64()` monotonic. https://github.com/ClickHouse/ClickHouse/issues/28087 needs `toDate()` to be monotonic.

BTW it's a Russian Cyrillic С not Latin С in the PR name " С lickhouse support" That's confusing , I copy/pasted Сlickhouse word and was unable to find it.
