As I always say when these sorts of articles come out (and I admit this is my use case for MongoDB and that doesn't necessarily match everyone else's use case), where is the easy to setup HA and sharding for PostgreSQL? I know it's coming, but right now it's not there.

For someone who redistributes a product that relies on end-users setting up HA, this for me is MongoDB's killer feature, easy to configure replication and sharding. I love PostgreSQL, but this is the one big thing that keeps me from using it right now.
