Update to 0.7.1

[josejachuf]

I use postgresql as a database.

1. I build the pool in this way

async fn make_db_pool(
    db_url: &str,
    min_connections: u32,
    max_connections: u32,
) -> Result<sqlx::Pool<sqlx::Postgres>, sqlx::Error> {
    let connection_options = PgConnectOptions::from_str(db_url).unwrap();
    connection_options.clone().disable_statement_logging();

    let pool = match PgPoolOptions::new()
        .min_connections(min_connections)
        .max_connections(max_connections)
        .connect_with(connection_options)
        .await
    {
        Ok(pool) => pool,
        Err(e) => return Err(e),
    };
    Ok(pool)
}

When I updated from 0.6.3 to 0.7.1 I started to obtain this message

WARN sqlx_core::pool::connection: error occurred while testing the connection on-release error=encountered unexpected or invalid data: unknown message type: '\0'

2. Bstr seems that it is not necessary to add it in the features at 0.7.1

# sqlx = { version = "0.6", features = [ "runtime-tokio-native-tls" , "postgres", "bstr" ] }
sqlx = { version = "0.7", features = [ "runtime-tokio-native-tls" , "postgres" ] }

the package my-app depends on sqlx, with features: bstr but sqlx does not have these features.

In the documentation the feature continues
