I've been pretty busy, and neglected this blog for a while, but I'm very happy that today I have been able to commit a parcel of new JSON functions that will be in the next PostgreSQL release. These include functions to create very complex JSON tree structures, and a function to aggregate pairs of values as JSON objects.
You can see some documentation in the development version Documents.
Thanks to Marko Tiikkaja for his timely review.
Stay tuned, there's more JSON goodness coming!
