How to open port with juju when no application is instlaled?

I believe there is an nginx charm, which you could have installed with
"juju deploy nginx --to X"  (where X is the machine id of the postgres
charm), and then used "juju expose nginx".
Is there a reason you prefer to install it manually?
One other option would be to co-locate the "ubuntu" charm and than use open
port from there, if you really don't want any other applications installed.
Generally we model ports-to-be-opened as part of an application, rather
than on a machine. So there's likely to be friction there without an
application to expose.
