-- 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 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.
