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.
