"Why would you want this over a NoSQL store?" If you can use a more general-purpose system like Postgres and get everything you need, then that's better than relying on special-purpose NoSQL systesm. The better question to ask is: why use a NoSQL system when Postgres works just fine and is useful in more situations? The history of databases is a history of absorbing special-purpose systems into general-purpose SQL systems. XML databases were once a major topic (albeit misguided); now it's just a feature. Same with Columnar storage, or OO databases, or geospatial (postgres is a leader in geospatial, as well). Because data integration is so incredibly valuable, it pushes strongly toward general-purpose systems and people dislike one-off special-purpose databases unless they deliver a huge amount of additional value.
