  def caveats; <<-EOS
If this is your first install, create a database with:
    #{HOMEBREW_PREFIX}/bin/initdb #{HOMEBREW_PREFIX}/var/postgres

Automatically load on login with:
    launchctl load -w #{prefix}/org.postgresql.postgres.plist

Or start manually with:
    #{HOMEBREW_PREFIX}/bin/pg_ctl -D #{HOMEBREW_PREFIX}/var/postgres -l #{HOMEBREW_PREFIX}/var/postgres/server.log start

And stop with:
    #{HOMEBREW_PREFIX}/bin/pg_ctl -D #{HOMEBREW_PREFIX}/var/postgres stop -s -m fast

If you want to install the postgres gem, include ARCHFLAGS in the gem install
to avoid issues:

    env ARCHFLAGS="-arch x86_64" gem install postgres

To install gems without sudo, see the Homebrew wiki.
