Как настроить PostgreSQL для Play 2.0?

Я хотел бы настроить PostgreSQL для своего приложения Play, но получаю следующее error:

! Internal server error, for request [GET /] ->

java.util.concurrent.TimeoutException: Futures timed out after [300000] milliseconds    at

~[play_2.9.1.jar:2.0]

Я использую следующие файлы конфигурации:

application.conf

db.default.url="postgres://play:play@localhost:9000/Play_Playground_DB"
db.default.user=play
db.default.password=play
db.default.driver=org.postgresql.Driver

project/Build.scala

val appDependencies = Seq(
  "postgresql" % "postgresql" % "9.1-901.jdbc4"
)

Я настроил Play_Playground_DBи могу получить к нему доступ через терминал и команду psql Play_Playground_DB.

В чем может быть основная причина проблемы?
