fetch() stream

[gitmalong]

Hi!

Is there something like a select, execute method that returns data as a Payload Stream similar to sqlx's fetch() method?

Thanks

Currently, it is not possible to take a Payload::{Select,SelectMap} as a futures::Stream.

This would be nice in the future when we have a Database Driver implementation that creates a Connection like sqlx.
