It looks like it wouldn't take too much work to replace
shared buffers on the basis of LRU-2 instead of LRU, so
I'm thinking about trying it.

Has anyone looked into this area? Is there a better method to try?

Sounds like a perfect idea. Good luck. :-)

Hmm, how much time will be required?
I integrate WAL right now and have to do significant changes
in bufmgr...

Don't worry about it, I am not planning to commit that code anytime
soon. (I have other stuff I want to fix in bufmgr, but I can wait
for you to finish WAL first.)
