The configure script seems to prefer this version of Python over any others,
so you may experience linker problems as described in:
http://osdir.com/ml/pgsql-general/2009-09/msg00160.html
To fix this issue, you may need to either delete the version of Python
shown above, or move it out of the way before brewing PostgreSQL.
Note that a framework Python in /Library/Frameworks/Python.framework is
the "MacPython" version, and not the system-provided version which is in:
/System/Library/Frameworks/Python.framework

# Build Notes
If builds of PostgreSQL 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/9.1/static/install-procedure.html
# Create/Upgrade a Database
If this is your first install, create a database with:
initdb #{var}/postgres
To migrate existing data from a previous major version (pre-9.1) of PostgreSQL, see:
http://www.postgresql.org/docs/9.1/static/upgrading.html
# Start/Stop PostgreSQL
If this is your first install, automatically load on login with:
mkdir -p ~/Library/LaunchAgents
cp #{plist_path} ~/Library/LaunchAgents/
launchctl load -w ~/Library/LaunchAgents/#{plist_path.basename}
If this is an upgrade and you already have the #{plist_path.basename} loaded:
launchctl unload -w ~/Library/LaunchAgents/#{plist_path.basename}
cp #{plist_path} ~/Library/LaunchAgents/
launchctl load -w ~/Library/LaunchAgents/#{plist_path.basename}
Or start manually with:
pg_ctl -D #{var}/postgres -l #{var}/postgres/server.log start
And stop with:
pg_ctl -D #{var}/postgres stop -s -m fast
# Loading Extensions
By default, Homebrew builds all available Contrib extensions. To see a list of all
available extensions, from the psql command line, run:
SELECT * FROM pg_available_extensions;
To load any of the extension names, navigate to the desired database and run:
CREATE EXTENSION [extension name];
For instance, to load the tablefunc extension in the current database, run:
CREATE EXTENSION tablefunc;
For more information on the CREATE EXTENSION command, see:
http://www.postgresql.org/docs/9.1/static/sql-createextension.html
For more information on extensions, see:
http://www.postgresql.org/docs/9.1/static/contrib.html
# Other
Some machines may require provisioning of shared memory:

To install postgresql ( and ossp-uuid ) in 32 bits mode; you may use --32-bit :
brew install postgresql --32-bit
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.
