      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

      When installing the postgres gem, including ARCHFLAGS is recommended:
        ARCHFLAGS="-arch x86_64" gem install pg

      To install gems without sudo, see the Homebrew documentation:
        https://docs.brew.sh/Gems,-Eggs-and-Perl-Modules

      This formula has created a default database cluster with:
        initdb #{postgresql_datadir}
      For more details, read:
        https://www.postgresql.org/docs/#{version.major}/app-initdb.html
