Looks like you are asking but if you ask me you just proved that it's enough..

I would suggest looking at pg metadata regarding memory usage as well as ipcs
stats. Besides what are the kernle disk buffer setting. I believe you are using
linux and these buffer settings can be controlled via/for bdflush.

Your typical ipcs usage would be a much valuable figure along with free..

And BTW, what's your vacuum frequency? Just to count that in..
