For posterity, here is the solution I ended up with:
def before_create
super
self.number ||= Sequel.function(:nextval, Sequel.function(:
pg_get_serial_sequence, self.class.table_name.to_s, 'order_number'))
end
This lets me specify an order number if desired, avoids a round trip to the
database, and doesn't require a pre-determined index name.
