AWS 宣佈 Amazon Aurora 也支援 PostgreSQL 了，相容於 9.6.3 的版本 (應該就是改自這個版本)：「Now Available – Amazon Aurora with PostgreSQL Compatibility」。
On the performance side, you can expect up to 3x the throughput that you’d get if you ran PostgreSQL on your own (you can read Amazon Aurora: Design Considerations for High Throughput Cloud-Native Relational Databases to learn more about how we did this).
架構上也是採用 6-way replication 的方式：
It is compatible with PostgreSQL 9.6.3 and scales automatically to support up to 64 TB of storage, with 6-way replication behind the scenes to improve performance and availability.
You can use Amazon Aurora with PostgreSQL Compatibility today in the US East (Northern Virginia), EU (Ireland), US West (Oregon), and US East (Ohio) Regions, with others to follow as soon as possible.
