    If builds of PostgreSQL 9 are failing and you have version 8.x installed,
    you may need to remove the previous version first. See:
      https://github.com/Homebrew/homebrew/issues/issue/2510

    To migrate existing data from a previous major version (pre-9.3) of PostgreSQL, see:
      http://www.postgresql.org/docs/9.3/static/upgrading.html

  def gem_caveats; <<-EOS.undent
    When installing the postgres gem, including ARCHFLAGS is recommended:
      ARCHFLAGS="-arch x86_64" gem install pg

    To install gems without sudo, see the Homebrew wiki.
