will db2_fdw in PostgreSQL will help me to do this?
You can't write to nicknames in triggers in Db2.
You may use SQL Replication to a federated data source (PostgreSQL in you case) depending on your Db2 version.

I have a PostgreSQL database . How I can migrate this to Amazon Web Service RDS??
I don't understand how to do it. Is it using Database Migration Service on AWS?
You can use AWS Database Migration Service, but that seems like an overkill if you migrate from PostgreSQL to PostgreSQL. Database Migration Service allows data migration between different RDBMS and even between NoSQL databases and RDBMS.
Just dump your database with pg_dump and restore it to RDS instance with pg_restore.
