==> 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.

Create a Database:

Erics-MacBook:~ eric$ createdb mydb

Open the mydb database and do some test:

Erics-MacBook:~ eric$ psql mydb
psql (9.0.1)
Type "help" for help.

mydb=# create table users(id serial, name varchar(25));
NOTICE:  CREATE TABLE will create implicit sequence "users_id_seq" for serial column "users.id"

bugs on OSX 10.8 Mountain Lion

> psql: could not connect to server: No such file or directory
    Is the server running locally and accepting
    connections on Unix domain socket "/var/pgsql_socket/.s.PGSQL.5432"?

mkdir /var/pgsql_socket
sudo chown $USER /var/pgsql_socket

Open /usr/local/var/postgres/postgresql.conf in a text editor, and uncomment + edit the unix_socket_directory key to:

unix_socket_directory = '/var/pgsql_socket'
