I'm somewhat excited about posix_fadvise but my general feeling was
that it was best to do nothing anyways. I don't know how to test these
questions though because they depend a lot on workload and pgbench or
synthetic queries which stress prefetching aren't especially good at
measuring how fast pages get evicted.
As far as reimplementing regular index scans -- I don't currently see
any way to do it in a way that would satisfy your demands that
wouldn't be insanely complex. Hopefully I'm missing something obvious
and if someone sees what I would be happy to go ahead and implement
something. But everything I've tried has turned into a monster.
