numactl shows the problem already:
Host system:
$ numactl --show
policy: default
preferred node: current
physcpubind: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19
cpubind: 0
nodebind: 0
membind: 0
preferred:
debian:trixie-slim container:
$ numactl --show
physcpubind: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19
No NUMA support available on this system.
debian:bookworm-slim container:
$ numactl --show
get_mempolicy: Operation not permitted
get_mempolicy: Operation not permitted
get_mempolicy: Operation not permitted
get_mempolicy: Operation not permitted
policy: default
preferred node: current
physcpubind: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19
cpubind: 0
nodebind: 0
membind: 0

Running with sudo does not change the result.
So maybe all that's needed is a get_mempolicy() call in
pg_numa_available() ?
