Not quite.
The json type as added in 9.2 (Sept 2012) and jsonb in 9.4 (Dec 2014). I
wouldn't call those far apart or very long ago. Neither included any
grammar changes AFAIR.
But if they had been added as extensions we'd probably be in a whole lot
more trouble now implementing SQL/JSON, so whether that was foresight or
laziness I think the we landed on our feet there.
