I mean, the JSON support in PostgreSQL is pretty freaking awesome now. Beyond the sharding, what are your few good reasons?

One thing I'd like to see in postgres is support for a superset of json, such as timestamps or binary data inside a json document.

Replication and failover don't look so great in postgres either.

Whenever I store binary data as text, I just base64 encode it and convert on the client.
