They tell you to use a proper FS, which is largely orthogonal to containerization.

WAL relies on shared memory, so while a proper FS is necessary, it isn't going to help in this case.

Why does it not help if both containers can mmap the same -shm file?

Shared memory across containers is a property of a containerization environment, not a property of a file system, "proper" or not.

It's a property of the filesystem, docker does not virtualize fs.

btw nfs that is mentioned here is fine in sync mode. However that is slow.
