7/// Native variants (`DateTime`/`NaiveDateTime`/`NaiveDate`/`Uuid`) are bound
8/// directly via `tokio_postgres`'s binary protocol (enabled by the
9/// `with-chrono-0_4`/`with-uuid-1` features). `Decimal` is bound as a string
10/// since `tokio_postgres` lacks a native `rust_decimal` adapter; PG's `NUMERIC`
11/// type accepts string input and round-trips losslessly.
