Hi, folks!
> I'll do more testing tomorrow, and hopefully finalize my patch.
Done! the patch is available at:
http://people.freebsd.org/~iwasaki/postgres/buffer-cache-hibernation-postgresql-20110508.patch
I hope this would be committable and the final version.
Major changes from the experimental implementation are the following.
- add many validations against hibernation file corruption and etc.
- restore buffer blocks based on buffer descriptors, not from the saved file.
- support restoring cache state even if shared_buffers had changed.
My vacation ends today and I have to go back my work from tomorrow,
but I would try to find spare time for this.
Thanks a lot for happy hacking days with you!
