Returns range of dates

Example

use diesel::dsl::daterange;
use diesel::pg::sql_types::RangeBound;
use time::{Date, macros::date};

diesel::insert_into(posts)
    .values(&[
       versions.eq(daterange(Some(date!(2020-01-01)), Some(date!(2021-01-01)), RangeBound::LowerBoundInclusiveUpperBoundInclusive)),
       versions.eq(daterange(None, Some(date!(2020-01-01)), RangeBound::LowerBoundInclusiveUpperBoundExclusive)),
    ]).execute(conn)?;

let cool_posts = posts.select(versions)
    .load::<(Bound<Date>, Bound<Date>)>(conn)?;
assert_eq!(vec![
         (Bound::Included(date!(2020-01-01)), Bound::Excluded(date!(2021-01-02))),
         (Bound::Unbounded, Bound::Excluded(date!(2020-01-01))),
     ], cool_posts);
