"synthetic benchmark" is doing some heavy lifting here. Pgbench just runs a bunch of SQL statements against a real Postgres instance.

It's very close to a real world simulation of a production workload

I am not questioning the benchmark. But the benchmark is NOT measuring a real world application in a real world setting. Anyway, I am merely wondering IF there is a company out there affected, at all. I understand that this was only measured on a graviton 4 setting with very heavy lifting, without huge tables.

For example, this issue aside, I'd rather split such a workload into multiple smaller instances, naturally. Because the impact of a crash on this single node, heavy load, many cores, many clients scenario would be huge.
