I have two PostgreSQL databases named data-1 and data-2 that sit on the same
machine. Both databases keep 40 GB of data, and the total memory available on
the machine is 68GB.
I started data-1 and data-2, and ran several queries to go over all their data.
Then, I shut down data-1 and kept issui
sed pages,
unused pages would eventually get evicted. Is there anything else we can try on
this host to understand why this is happening?
Thank you,
Metin

Hi,
Yes data-2 is bigger than half of memory. I'm willing to try those patches.
This is the version of this machine:
$ uname -r
3.2.28-45.62.amzn1.x86_64

memory. So I hope your patches will
take place in the soonest linux kernel version.
Thanks,
Metin
