It is not from the exit. I see the exact same problem and I never
restart postgres and it never crashes. It runs constanty and with no
crashes for 20-30 days until the box is out of memory and I have to
reboot.

It is possible that it has already been fixed. I am seeing this memory
leak quite clearly on 2.6.12.6, but there's no evidence of it at all
on 2.6.16.27. The changelogs between those two versions show a lot of
bugfixes for memory leaks.
Also, that message from Will Glenn references a discussion where
someone else running 2.6.12 was having a memory leak issue.
