ActiveRecord support for citext

Adds support for citext to active_record

Add this line to your application's Gemfile:

gem 'activerecord-postgresql-citext'

And then execute:

$ bundle

Or install it yourself as:

$ gem install activerecord-postgresql-citext

In a database migration you need to first enable citext as an extension, then you can create columns of type citext.

def up
  enable_extension("citext")                   
                                             
  create_table :models, :force => true do |t|  
    t.citext :name                             
    t.timestamps                               
  end                                          
end
