Just did a simple bundle update and got an annoying error related to the pg gem for PostgreSQL. I don't have PostgreSQL installed on my system (unless it's automatically installed for Mac OS X 10.9.1). This has never been an issue before. Any ideas?

UPDATE 2: The only mention of pg in my Gemfile is here:
group :development do
gem 'sqlite3'
end
group :production do
gem 'pg'
end
The easiest way is to install Postgres.app.
Then do:
$ gem install pg -v '0.17.1' && bundle update
Edit: Do not forget to add the relevant directories into your PATH.
