The answer is wrong. It is not supported.
It is support only for MySQL, version 5.6 or above
Amazon RDS for MySQL: You can create a second-tier Read Replica from an existing first-tier Read Replica. By creating a second-tier Read Replica, you may be able to move some of the replication load from the master database instance to a first-tier Read Replica. Please note that a second-tier Read Replica may lag further behind the master because of additional replication latency introduced as transactions are replicated from the master to the first tier replica and then to the second-tier replica.
Amazon RDS for PostgreSQL: Read Replicas of Read Replicas are not currently supported.
