Fix PostgreSQL Mavericks

gistfile1.txt

brew install postgresql

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/Homebrew/homebrew/issues/issue/2510

To migrate existing data from a previous major version (pre-9.3) of PostgreSQL, see:
  http://www.postgresql.org/docs/9.3/static/upgrading.html

When installing the postgres gem, including ARCHFLAGS is recommended:
  ARCHFLAGS="-arch x86_64" gem install pg

To install gems without sudo, see the Homebrew wiki.

To reload postgresql after an upgrade:
    launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
    launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
    

env ARCHFLAGS="-arch x86_64" gem install pg -- --with-pg-config=/usr/local/Cellar/postgresql/9.3.4/bin/pg_config



Postgres.app
gem install pg -- --with-pg-config=/Applications/Postgres.app/Contents/Versions/9.3/bin/pg_config
