How to use
---------

Add phoenix_pubsub_postgres to your mix deps

    defp deps do
      [{:phoenix, github: "phoenixframework/phoenix", override: true},
       {:phoenix_pubsub_postgres, "~> 0.0.2"},
       {:postgrex, ">= 0.0.0"},
       {:cowboy, "~> 1.0"}]
    end

To use Postgres as your PubSub adapter, simply add it to your Endpoint's config and modify it as needed.

    config :my_app, MyApp.Endpiont,
      ...
      pubsub: [name: MyApp.PubSub,
               adapter: PhoenixPubSubPostgres,
               hostname: "localhost",
               database: "myapp_db_env",
               username: "postgres",
               password: "postgres"]
