I sent a message describing where I was headed with the code and my
misgivings with Tom's concerns. I haven't seen any responses.
Hmmm. I can't find my message however so now I'm wondering if it ever
hit the lists.

Implement prefetching via posix_fadvise() for bitmap index scans.
A new
GUC variable effective_io_concurrency controls how many concurrent
block
prefetch requests will be issued.
(The best way to handle this for plain index scans is still under

so that part is not applied yet --- tgl)
Where are we on completing this feature?
