Why can't I create an array as a column in a table in Rails?

Question

Why can\'t I do something like this:

class CreateModels < ActiveRecord::Migration
  def self.up
    create_table :fruit do |t|
      t.array :apples
    e

In Rails 4 and using PostgreSQL you can actually use an array type in the DB:

Migration:

class CreateSomething < ActiveRecord::Migration
  def change
    create_table :something do |t|
      t.string :some_array, array: true, default: []
      t.timestamps
    end
  end
end
