As already pointed out, you won't find such a benchmark.

You will have to run such a benchmark yourself. Ideally with a workload
that represents your use case. Or maybe with something like HammerDB.

But Exadata isn't only software, it's also hardware especially designed
to work together with Oracle's enterprise edition.

So if you want to get any reasonable results, you will at least have to
buy hardware that matches the Exadata HW specifications.

So if you run your own tests, make sure you buy comparable HW for
Postgres as well (lots of RAM and many fast server grade NVMes)
