      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/legacy-homebrew/issues/2510

      To migrate existing data from a previous major version (pre-9.3) of PostgreSQL, see:

        \nWhen installing the postgres gem, including ARCHFLAGS is recommended:

        To install gems without sudo, see the Homebrew documentation:
