What is POSIX shared memory used for anymore? Shared buffers now defaults to mmap, right? So when I run out of shm in Kubernetes because of the 64MB limit, what is actually causing it to run out?

(I know about creating the memory-based volume and mounting it at /dev/shm, and have implemented that workaround. Still want to know what is causing this memory use.)
