It seems to me that you are creating those too early. For example, for
a background worker process, DSA segments would likely be created in
the main process routine. Without understanding what you are trying to
achieve, it is hard to make a good answer. You could always use a
ramdisk, but that would be likely be a waste of memory as Postgres has
its own buffer pool, killing the performance gains of OS caching.
