Hi, everyone
I am writing to ask if the recently introduced RWF_DONTCACHE [0] (originally named RWF_UNCACHE) in the Linux kernel
willbe or is already supported by PostgreSQL?
I am not sure if RWF_DONTCACHE will improve PostgreSQL performance. In fact, I think it may even degrade performance.
Hasanyone tested this?

Thanks, everyone.
