	==> Caveats
	If builds of Postgresl 9 are failing and you have version 8.x installed,
	you may need to remove the previous version first. See:
	  https://github.com/mxcl/homebrew/issues/issue/2510

	To build plpython against a specific Python, set PYTHON prior to brewing:
	  PYTHON=/usr/local/bin/python  brew install postgresql
	See:
	  http://www.postgresql.org/docs/9.0/static/install-procedure.html


	If this is your first install, create a database with:
	    initdb /usr/local/var/postgres

	If this is your first install, automatically load on login with:
	    cp /usr/local/Cellar/postgresql/9.0.1/org.postgresql.postgres.plist ~/Library/LaunchAgents
	    launchctl load -w ~/Library/LaunchAgents/org.postgresql.postgres.plist

	If this is an upgrade and you already have the org.postgresql.postgres.plist loaded:
	    launchctl unload -w ~/Library/LaunchAgents/org.postgresql.postgres.plist
	    cp /usr/local/Cellar/postgresql/9.0.1/org.postgresql.postgres.plist ~/Library/LaunchAgents
	    launchctl load -w ~/Library/LaunchAgents/org.postgresql.postgres.plist

	Or start manually with:
	    pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start

	And stop with:
	    pg_ctl -D /usr/local/var/postgres stop -s -m fast

	If you want to install the postgres gem, including ARCHFLAGS is recommended:
	    env ARCHFLAGS="-arch x86_64" gem install pg

	To install gems without sudo, see the Homebrew wiki.

Init Database:
	Erics-MacBook:~ eric$ initdb /usr/local/var/postgres
	The files belonging to this database system will be owned by user "eric".
	This user must also own the server process.

	The database cluster will be initialized with locale en_US.UTF-8.
	The default database encoding has accordingly been set to UTF8.
	The default text search configuration will be set to "english".

	or
	    pg_ctl -D /usr/local/var/postgres -l logfile start
