# 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 +uuid_generate_v4()+ function from the
# +uuid-ossp+ extension, which MUST be enabled on your database. To enable
# the +uuid-ossp+ extension, you can use the +enable_extension+ method in your
# migrations. To use a UUID primary key without +uuid-ossp+ enabled, you can
# 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 different UUID generation function from +uuid-ossp+
# or 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.
