// 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.
//
// This command doesn't apply to RDS Custom.
//
// 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 [Amazon RDS console]or the DescribeDBParameters command to verify
// that your DB parameter group has been created or modified.
//
// [Amazon RDS console]: https://console.aws.amazon.com/rds/
