        # Defines the primary key field.
        # Use of the native PostgreSQL UUID type is supported, and can be used
        # by defining your tables as such:
        #
        #   create_table :stuffs, id: :uuid do |t|
        #     t.string :content
        #     t.timestamps
        #   end
        #
        # By default, this will use the +gen_random_uuid()+ function from the
        # +pgcrypto+ extension. As that extension is only available in
        # PostgreSQL 9.4+, for earlier versions an explicit default can be set
        # to use +uuid_generate_v4()+ from the +uuid-ossp+ extension instead:
        #
        #   create_table :stuffs, id: false do |t|
        #     t.primary_key :id, :uuid, default: "uuid_generate_v4()"
        #     t.uuid :foo_id
        #     t.timestamps
        #   end
        #
        # To enable the appropriate extension, which is a requirement, use
        # the +enable_extension+ method in your migrations.
        #
        # To use a UUID primary key without any of the extensions, set the
        # +:default+ option to +nil+:
        #
        #   create_table :stuffs, id: false do |t|
        #     t.primary_key :id, :uuid, default: nil
        #     t.uuid :foo_id
        #     t.timestamps
        #   end
        #
        # You may also pass a custom stored procedure that returns a UUID or use a
        # different UUID generation function from another library.
        #
        # Note that setting the UUID primary key default value to +nil+ will
        # require you to assure that you always provide a UUID value before saving
        # a record (as primary keys cannot be +nil+). This might be done via the
        # +SecureRandom.uuid+ method and a +before_save+ callback, for instance.
