streaming replication on-premise posgresql(src) -> aws rds postgresql (dst)

Hi, this post is about Oracle but, to confirm Riku's statement, it validate that on-prem to RDS is possible. See https://aws.amazon.com/blogs/database/achieve-a-high-performance-migration-to-amazon-rds-for-oracle-from-on-premises-oracle-with-aws-dms/

Unfortunately, DMS is a way way different from streaming replication. DMS with validation and CDC is a pain. Streaming replication always works like a charm and you don't need to think about indexes, sequences, views, foreign keys and so on.
