Diesel Connect to Postgres via ssl not working

Is it only me but when I specify sslmode=require in database url, error is thrown

DatabaseError(UnableToSendCommand, "error performing TLS handshake: no TLS implementation configured")

Already raised issue diesel does not connection to postgres database with `sslmode` required · Issue #3317 · diesel-rs/diesel · GitHub

Yall think this is a bug because it worked fine with mysql!?
