// Modifies the parameters of a DB parameter group. To modify more than one
// parameter, submit a list of the following: ParameterName , ParameterValue , and
// ApplyMethod . A maximum of 20 parameters can be modified in a single request.
//
// After you modify 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 modify
// operation 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 [Amazon RDS console]or the DescribeDBParameters command to
// verify that your DB parameter group has been created or modified.
