This topic describes the use scenarios of the service-linked roles that are supported by ApsaraDB RDS. This topic also describes how to delete the service-linked roles.

Background information

ApsaraDB RDS supports the following service-linked roles:

AliyunServiceRoleForRdsPgsqlOnEcs, which is used for ApsaraDB RDS for PostgreSQL
AliyunServiceRoleForRDSProxyOnEcs, which is used for the database proxy feature of ApsaraDB RDS for PostgreSQL

ApsaraDB RDS may require access to other Alibaba Cloud services to provide specific features. You can assign a service-linked role to ApsaraDB RDS to obtain the permissions that are required to access other Alibaba Cloud services. A service-linked role is a RAM role.
