openacs.org is still using PG 7.2.4 I believe.
There are other sites that are also using that instance of PG 7.2 on that machine, IIRC. We'd definitely want to upgrade to a newer version of PG when we upgrade the site.
It'd be really nice if we could have different machines answering for openacs.org. I don't have experience with this, and it would be really nice if those who do (sloan, greenpeace, etc.) could post what they have in their setups so we could learn and apply.
I read an interesting report about livejournal.com and the memcached distributed memory caching daemon they came up with. It'd be applicable for oacs.org if we had more thatn one machine answering for oacs.org on the same network.
