Hi Christoph,

Could you please let me know what is the process to enable -moutline-atomics for arm64 binaries distributed by PostgreSQL for Ubuntu 20.04?
Using the right LSE atomic instructions is very important for the performance of PostgreSQL on all new arm64 processors.
Please let me know how I can help to enable the flag, test, and benchmark the new packages.

Thanks,
Sebastian
