I am getting following error:

label: the trait `bb8_postgres::tokio_postgres::tls::MakeTlsConnect<bb8_postgres::tokio_postgres::Socket>` is not implemented for `tokio_postgres::NoTls`

You have a version mismatch going on. You need to use bb8 from master to be able to use tokio-postgres 0.5 (I hope to release a new version of bb8 soon).
