postgres: nie można zainstalować postgresql-contrib-9.1

Moja wersja systemu to Ubuntu 13.10 64bit.

Napotkałem ten problem, konfigurując PostgreSQL w aplikacji Rails.

Najpierw pobiegłem rake db:migrate i pokazał błąd:

-- enable_extension("hstore")
rake aborted!
StandardError: An error has occurred, this and all later migrations canceled:
