Loving those JSON improvements. Looking forward to migrating away from jsonb_build_object and its ilk. They served me well, but were hardly elegant. Now the JSON can look more like... well... JSON.<p>MERGE will definitely fill in some logical gaps for me as well. A bit wordy but super powerful. Unlike the logic in application tier, there can now be true transactional safety instead of "good enough with the occasional error and/or clean up script" that happens now. Data consistency belongs in the database, not the app.
