Breaking changes

Any service that used the (shared Postgres) PgPool would have had the following main function:

async fn rocket(pool: PgPool) -> shuttle_service::ShuttleRocket {
    // Create service here
}

And a sqlx-postgres feature for shuttle-service. With the support of more databases, this PgPool now needs to explicitly define what kind of database instance it will connect to using argument attributes. This can be done by adding #[shared::Postgres] to the attribute:

async fn rocket(#[shared::Postgres] pool: PgPool) -> shuttle_service::ShuttleRocket {
    // Create service here
}
