Installing PostgreSQL on my Mac

November 30th, 2010 by Brian | Filed under work.

PostgreSQL

1.  Download postgres for Mac

  • Don’t sign up for enterprise db crap, the download will start in a sec

2. Install postgres

  • This may require reboot to set some syscontrol settings (it did for me)
  • I created the “postgres” user with “postgres” as the password (so I could remember it)

3. Add stuff to your ~/.bash_profile

export PATH=$PATH:/Library/PostgreSQL/9.0/bin
export PGDATA=/Library/PostgreSQL/9.0/data

4. Execute the profile

$ . ~/.bashrc

5. Modify Postgres to use “trust” authentication, so we don’t need to supply a password when connecting to the database.

$ sudo vi /Library/PostgreSQL/9.0/data/pg_hba.conf

5.1 For each entry, change METHOD “md5″ to “trust” (this should only be done on your developer machine!)

6. Restart postgres to pick up the conf changes

$ sudo su – postgres
$ . ./pg_env.sh
$ pg_ctl restart

7. Beer time!

All of the above was done solely so I could run some ActiveRecord tests, so here’s how we do that:

$gem install pg
$ git clone git://github.com/rails/rails.git
$ cd rails/activerecord
$ rake postgresql:build_databases
$ rake test_postgresql TEST=test/cases/base_test.rb
(in /Users/brian/dev/ruby/rails/activerecord)

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby -w -I"lib:test:test/connections/native_postgresql" "/Users/brian/.gem/ruby/1.8/gems/rake0.8.7/lib/rake/rake_test_loader.rb" "test/cases/base_test.rb"

    You forgot to give us the password for your mac.
