Моя системная версия - Ubuntu 13.10 64bit.
Я столкнулся с этой проблемой, настроив PostgreSQL в приложении Rails.
Сначала я запустил rake db:migrate и он показал ошибку:
-- enable_extension("hstore")
rake aborted!
StandardError: An error has occurred, this and all later migrations canceled:

После некоторого поиска я нашел сообщение на SO, указывающее, что я могу запустить
sudo apt-get install postgresql-contrib-9.1
Но тогда я получил то, что получил
Reading package lists... Done

Package postgresql-contrib-9.1 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:

E: Package 'postgresql-contrib-9.1' has no installation candidate
