I guess we should not replace current JSON type with hstore based

Well, that's two voices for that course of action.

Interesting that I don't think I heard a single voice for this either at pgCon or pgOpen, although I spent large amounts of time at both talking to people about Json, so I'd be interested to hear more voices.

It would actually simplify things in a way if we do that - we've been working on a way of doing this that wouldn't upset pg_upgrade. This would render that effort unnecessary.

However it will complicate things for users who will have to choose between the data types, and function authors who will possibly have to write versions of functions to work with both types.

Also most of the current json functions should also be moved to work on
jsobj instead with explicit cast from json to jsobj

Sure, we can overload them - that's probably the least of our worries.
