postgreSQL の覚え書き
Homebrew で postgreSQL をインストールすると途中で設定方法などが表示される。
書籍のやり方とちょっと違うのでメモ程度に残す。
# 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/9.1.3/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/9.1.3/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.
