You can call the DeleteParameterGroup operation to delete a parameter template of an ApsaraDB RDS instance.

You can apply a parameter template to an instance to configure a number of parameters at a time. For more information, see Use a parameter template to configure the parameters of ApsaraDB RDS for MySQL instances or Use a parameter template to configure the parameters of ApsaraDB RDS for PostgreSQL instances.

Note
  • If you delete a parameter template, the instances to which the parameter template is applied are not affected.
  • Before you can delete a parameter template in ApsaraDB RDS for PostgreSQL, you must apply another parameter template to the ApsaraDB RDS for PostgreSQL instances to which the parameter template is applied. You can call the DescribeParameterGroup operation to query the instances to which the parameter template is applied.
