As I understand the term used, there is no scheduler inside Postgres for user connections -- they're handled by the OS kernel. That's probably why it'd be a difficult project to be smart about memory -- step one might be to invent a scheduler. (The autovacuum launcher and checkpointer, etc have their own logic about when to do things, but while running they too are just OS processes scheduled by the kernel.)
