Is Amazon RDS cheaper than Cloud SQL?
Short answer: it depends on your workload. Amazon RDS bills around the clock; Cloud SQL bills around the clock. The two cases below flip the answer.
Amazon RDS: Managed Postgres on AWS, billed around the clock per instance. It bills per instance-hour, 24/7, no scale-to-zero.
Cloud SQL: Managed Postgres on Google Cloud, priced per vCPU and RAM. It bills per vCPU-hour + per GB-RAM-hour, 24/7.
So Amazon RDS is cheaper than Cloud SQL for bursty or idle databases, and more expensive for the other. Your real answer depends on your compute size, how many hours a day the database is active, and your storage.
