Configure Postgres
------------------

* Update `pg_hba.conf` (most likely in `/etc/postgresql/9.4/main`) with -
    * `host all all 0.0.0.0/0 trust`
    * (you can, alternatively, set the IP to something more specific)
* Update `postgresql.conf` to use `listen_addresses = '*'`
* Be sure to `sudo service postgresql restart`

Configure Vagrant
-----------------

* Add `config.vm.network :forwarded_port, host: 5432, guest: 5432` to the `Vagrant.configure` block in your `Vagrantfile`.

Test your connection
--------------------

* Attempt to connect from your host using `psql -h localhost -U vagrant`
