A lot of treats in this release! Amongst the new big features (cascaded replication, index only scans) I'm really happy to see a row->json function (great for message queues), DROP INDEX CONCURRENTLY (more flexibility to play with indexes even on production servers), NOT VALID CHECK constraints allowing us to slowly roll out more integrity, and a few other things. Great work as always!
