Mac OSX 和 posgresql (2013再次更新版)

UPDATE(2013/06/01)

brew services restart postgresql
psql -U kenlu -h localhost -d postgres

几个重要说明：
1. mac 下brew安装后要initdb
2. 启动后，默认管理员是系统当前帐户
3. psql不认的时候，就是brew的路径问题（见下代码）
4. brew装的重启，启动什么的用brew services

在ubuntu下完全不同sudo aptitude 安装后，不许要initdb只要

sudo -u postgres psql template1
template1=# CREATE USER tom WITH PASSWORD 'myPassword';
ALTER USER postgres with encrypted password 'your_password';
grant all privileges on database postgres to postgres; 
alter user livegamer with superuser; 
sudo nano /etc/postgresql/9.1/main/postgresql.conf
#localhost

mac下用brew装posgresql
然后，有个说明很不错，只是记录过程

initdb /usr/local/var/postgres -E utf8

postgres -D /usr/local/var/postgres

psql postgres `whoami`

$ echo 'export PATH=/usr/local/bin:$PATH' >> ~/.bash_profile && . ~/.bash_profile

brew install postgres

initdb /usr/local/var/postgres

cp /usr/local/Cellar/postgresql/9.1.4/homebrew.mxcl.postgresql.plist ~/Library/LaunchAgents/

launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist

createuser
(postgres)



sudo -u postgres psql

ALTER USER postgres with encrypted password 'your_password';  

vim /usr/local/var/postgres/postgresql.conf


listen_addresses = 'localhost' => listen_addresses = '*'

psql -U postgres -h localhost

# 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.
