How does RDS replicate a Postgres database through multiple availability zones

Is there some kind of native Postgres tool they use, or is it a custom one? Are the replicas always in sync or do they drift apart from time to time?

With Multi-AZ RDS replication is synchronous. And since AWS like to be in full control of their software, it’s most likely a customised replication (but I couldn’t tell you for sure).
