क्या यह आपकी पहली स्थापना है? क्या आपने दौड़ने की कोशिश की है initdb /usr/local/var/postgres? यह सिर्फ उसी मुद्दे को हल करता है, जो होमबॉव का उपयोग करके एक पुराने सिस्टम-वाइड पोस्टग्रेक्यूएल को स्थापित करने और इसे फिर से स्थापित करने के बाद अभी हुआ है।
brew info postgresपैकेज स्थापित करने के बाद उपलब्ध कमांड के रिमाइंडर के रूप में रनिंग हमेशा उपयोगी होती है।

==> Caveats
# 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 /usr/local/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 /usr/local/Cellar/postgresql/9.1.4/homebrew.mxcl.postgresql.plist ~/Library/LaunchAgents/
launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
If this is an upgrade and you already have the homebrew.mxcl.postgresql.plist loaded:
launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
cp /usr/local/Cellar/postgresql/9.1.4/homebrew.mxcl.postgresql.plist ~/Library/LaunchAgents/
launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.postgresql.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
# 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:
http://www.postgresql.org/docs/current/static/kernel-resources.html#SYSVIPC
To install postgresql (and ossp-uuid) in 32-bit mode:
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.
