Use of re-exported sqlx causes macros to throw extensive errors

[utopiabound]

From one package in a project:
project/sub-postgres/src/lib.rs

pub use sqlx::{self, postgres::PgPool};
...

project/sub-usepsql/src/lib.rs

use sub_postgres::sqlx::{self, PgPool};
...
let foo = query!(...)

With sqlx 0.4 this worked just fine.
WIth sqlx 0.5 (because of 76326c6) This throws extensive errors if sqlx isn't also included in project/sub-usepsql/Cargo.toml

That this worked on 0.4 was not intentional. Generally proc-macros are expected to work regardless of other items in the crate or module, and if the macros looked for sqlx (0.4 behaviour) instead of ::sqlx (0.5 behaviour), they would break if there was a local module named sqlx that doesn't re-export a bunch of stuff from the sqlx crate.

If you are annoyed by having to re-specify the version and features for your dependencies in multiple crates of your workspace, I suggest watching rust-lang/cargo#8415.
