I'm fine with that. I'd like the strip-Nulls capability, but seems like it'd be better off as an independent function (or functions) instead.

Unlike the row_to_json stuff, json{b}_strip_null_fields() can almost certainly be done as a small extension. One advantage of that is that it would be used with 9.4.
