migration fail with postgresql and ruby 1.9.1

Hi,

I don't know if it's active record bug or one from postgresql driver, but the following migration give's an error with ruby 1.9.1 (work fine with ruby 1.8.6) :

require 'active_record' class SomeMigration < ActiveRecord::Migration def self.up

create_table "tramp_accounts" do |t|
  t.string   "code"
  t.string   "label"
  t.string   "orientation"
  t.boolean  "agregator"
  t.integer  "parent_id"
  t.datetime "created_at"
  t.datetime "updated_at"
end

end end ActiveRecord::Base.establish_connection(:adapter=>'postgresql',

                                    :database=>'tramp_test',
                                    :username=>'postgres')

SomeMigration.migrate(:up)
