Re: [PATCH] audo-detect and use -moutline-atomics compilation flag for aarch64

Thanks Christoph for the quick turn-around.

I see that builds with -moutline-atomics succeeded for Focal arm64 builds for all the branches:
https://pgdgbuild.dus.dg-i.net/view/PostgreSQL/job/postgresql-9.6-binaries/architecture=arm64,distribution=focal/88/
https://pgdgbuild.dus.dg-i.net/job/postgresql-10-binaries/77/architecture=arm64,distribution=focal/
https://pgdgbuild.dus.dg-i.net/view/PostgreSQL/job/postgresql-11-binaries/architecture=arm64,distribution=focal/686/
https://pgdgbuild.dus.dg-i.net/view/PostgreSQL/job/postgresql-12-binaries/architecture=arm64,distribution=focal/875/
https://pgdgbuild.dus.dg-i.net/view/PostgreSQL/job/postgresql-13-binaries/architecture=arm64,distribution=focal/858/
https://pgdgbuild.dus.dg-i.net/view/PostgreSQL/job/postgresql-14-binaries/architecture=arm64,distribution=focal/651/

I see that the patch is still missing on branch 15 that is the development branch:
https://pgdgbuild.dus.dg-i.net/view/PostgreSQL/job/postgresql-15-binaries/architecture=amd64,distribution=focal/345/
Maybe we need to add the patch to that branch as well?

How are the above binaries distributed to users?
I see for instance that pgsql 14 binaries have last been updated in 30-Sep-2021:
https://apt.postgresql.org/pub/repos/apt/dists/focal-pgdg/14/binary-arm64/
Is there another step needed to make those binaries available through the PostgreSQL Apt Repository (
https://www.postgresql.org/download/linux/ubuntu/) 

Does Canonical rely on these builds to update the Focal PostgreSQL packages?

Thanks,
Sebastian
