Suggested next steps:

    * Create a user for postgresql (we'll name it "postgres"). Do it via System preferences or by running:

    $ sudo dscl . -create /Users/postgres
    $ sudo dscl . -create /Users/postgres Usershell /bin/bash

    * Create a databse:

    $ sudo mkdir -p /var/db/postgresql/defaultdb
    $ sudo chown postgres /var/db/postgresql/defaultdb
    $ sudo su postgres -c '#{HOMEBREW_PREFIX}/bin/initdb -D /var/db/postgresql/defaultdb'

    $ sudo touch /var/log/postgres.log
    $ sudo chown postgres /var/log/postgres.log

Starting:

    $ sudo su postgres -c "#{HOMEBREW_PREFIX}/bin/pg_ctl -D /var/db/postgresql/defaultdb start -l /var/log/postgres.log"

Stopping:

    $ sudo su postgres -c "#{HOMEBREW_PREFIX}/bin/pg_ctl -D /var/db/postgresql/defaultdb stop -s -m fast"

You can also alias the above commands in your bash profile to pg_start and pg_stop.

Google around for org.postgresql.plist if you want launchd support.

If you're wanting to install the postgres gem, include ARCHFLAGS in the gem install to avoid issues:

sudo env ARCHFLAGS="-arch x86_64" gem install postgres
    EOS
  end
