-- Creates a new DB parameter group.
--
-- A DB parameter group is initially created with the default parameters
-- for the database engine used by the DB instance. To provide custom
-- values for any of the parameters, you must modify the group after
-- creating it using /ModifyDBParameterGroup/. Once you\'ve created a DB
-- parameter group, you need to associate it with your DB instance using
-- /ModifyDBInstance/. When you associate a new DB parameter group with a
-- running DB instance, you need to reboot the DB instance without failover
-- for the new DB parameter group and associated settings to take effect.
--
-- After you create a DB parameter group, you should wait at least 5
-- minutes before creating your first DB instance that uses that DB
-- parameter group as the default parameter group. This allows Amazon RDS
-- to fully complete the create action before the parameter group is used
-- as the default for a new DB instance. This is especially important for
-- parameters that are critical when creating the default database for a DB
-- instance, such as the character set for the default database defined by
-- the 'character_set_database' parameter. You can use the /Parameter
-- Groups/ option of the
-- <https://console.aws.amazon.com/rds/ Amazon RDS console> or the
-- /DescribeDBParameters/ command to verify that your DB parameter group
-- has been created or modified.
