Subject: DBShell::Client::Postgres: Convert port to string

Turns out the port actually did need to be a string, contrary to what I
had assumed in e89275bc787ae17bc698ac8cdb8cdaf5ebeb7852. I ended up with
this error when passing a specific port in a real test:

    $ bake dbshell
    rake aborted!
    TypeError: no implicit conversion of Fixnum into String
