After my experience with MongoDB at scale - I was running one of the largest MongoDB installations in the world according to 10gen - I have since run into the arms of postgres and wish to never repeat the horrors I experienced over there.

I think the main issue is that people want something to be simple, and now that I'm dealing with the somewhat esoteric and opaquely documented postgres, I can understand that feeling. Native replication and auto-failover (via pgpool) is a bit of a black box on postgres, but under MongoDB it was fairly simple.

The problem is, it's complicated for a reason, and that reason is scale. What took me over 100 masters in MongoDB will only need two postgres boxes, so it's worth dealing with the Oracle of Open Source to make it happen.
