-- Detaches a virtual private gateway from a VPC. You do this if you\'re
-- planning to turn off the VPC and not use it anymore. You can confirm a
-- virtual private gateway has been completely detached from a VPC by
-- describing the virtual private gateway (any attachments to the virtual
-- private gateway are also described).
--
-- You must wait for the attachment\'s state to switch to 'detached' before
-- you can delete the VPC or attach a different VPC to the virtual private
-- gateway.
