I still think Tom's suggestion is the best and simplest way to do that.
which Toms suggestion you mean here ?

The 3. mentioned above was for making possible 2 separate ways to convert (serialise/quote/escape and parse/check-for-valid-json) string to json and afair not about hstore to json.

Er, what? yes, I meant option 3, and it is a perfect mechanism for doing conversion of an hstore field inside datum_to_json: the code would look for a cast to the new type (whatever we call it) and use that instead of the normal text representation.


I'm also looking forward for an easy way or two to populate a record from json and extract an array from json.


I am prepared to take this on - at least starting with json to array which I think is the simpler case. I have some ideas about how to do this and have done a bit of experimental work along these lines. Personally I'd be inclined to make it do a conversion to text[] and then cast from that to anything else we needed.

cheers
