Thank you!

I want to add something about the (huge effort) of binder:

"""
We have reworked the way drivers work in SeaQuery: priori to 0.27, users have to invoke the sea_query_driver* macro. Now each driver sqlx, postgres & rusqlite has their own supporting crate, which integrates tightly with the corresponding libraries.

// before
sea_query::sea_query_driver_postgres!();
use sea_query_driver_postgres::{bind_query, bind_query_as};

    let (sql, values) = Query::select()
        .from(Character::Table)
        .expr(Func::count(Expr::col(Character::Id)))
        .build(PostgresQueryBuilder);

    let row = bind_query(sqlx::query(&sql), &values)
        .fetch_one(&mut pool)
        .await
        .unwrap();

// now
use sea_query_binder::SqlxBinder;

    let (sql, values) = Query::select()
        .from(Character::Table)
        .expr(Func::count(Expr::col(Character::Id)))
        .build_sqlx(PostgresQueryBuilder);

    let row = sqlx::query_with(&sql, values)
        .fetch_one(&mut pool)
        .await
        .unwrap();

// You can now make use of SQLx's `query_as_with` nicely:

    let rows = sqlx::query_as_with::<_, StructWithFromRow, _>(&sql, values)
        .fetch_all(&mut pool)
        .await
        .unwrap();

I also think it's worth giving examples for SeaQL/sea-query#347 "Table Column with Default Expression" and "InsertStatement::values, UpdateStatement::values now accepts IntoIterator<Item = SimpleExpr> instead of IntoIterator<Item = Value>"
and "Added OnConflict::value and OnConflict::values"

@tyt2y3 thank you for review! Done!
