  def caveats
    <<~EOS
      To build plpython against a specific Python, set PYTHON prior to brewing:
        PYTHON=/usr/local/bin/python brew install #{name}
      See:
        https://www.postgresql.org/docs/8.4/static/install-procedure.html


      If this is your first install, create a database with:
          initdb #{var}/#{name}

      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.
