-- | Creates an Amazon Redshift parameter group.
--
-- Creating parameter groups is independent of creating clusters. You can
-- associate a cluster with a parameter group when you create the cluster. You
-- can also associate an existing cluster with a parameter group after the
-- cluster is created by using 'ModifyCluster'.
--
-- Parameters in the parameter group define specific behavior that applies to
-- the databases you create on the cluster. For more information about managing
-- parameter groups, go to <http://docs.aws.amazon.com/redshift/latest/mgmt/working-with-parameter-groups.html Amazon Redshift Parameter Groups> in the /AmazonRedshift Cluster Management Guide/.

-- associated with the default parameter groups provide you the valid values.
