I implement 2Q algorithm to PostgreSQL for buffer management , instead
of LRU.
It's known as low overhead and high performance than LRU. If you have
some interests , see following URL.


In my test (pgbench -S) , it improves 4% cache hit rate and 2% up
performance comparing from LRU.

Do you have any interest about this patch?
