 Get the .dmg

There is a one-click installer available for PostgreSQL on Mac OS X. It packages the database up as a .dmg file. It is available here: http://www.enterprisedb.com/products/pgdownload.do#osx
Edit your PATH

The .dmg does the installation and setup, but it doesn't alter your PATH variable to include the PostgreSQL tools. To do this, edit

~/.bash_profile

and add the lines
