I'm not sure which of those options is better. I'm a bit worried just
accepting the alternative output would hide some failures in the future
(although it's a low risk).

So I'm leaning to adjust pg_numa_init() to also check EPERM, per the
attached patch. It still calls numa_available(), so that we don't
silently miss future libnuma changes.

Can you check this makes it work inside the docker container?
