This comment does not mention the version used, but it mentions the
JSON features of a "couple of months back", so I would guess that they
tried with 9.4.0 and jsonb. Now I recall as well the following bug:
http://www.postgresql.org/message-id/20140731233051.GN17765@andrew-ThinkPad-X230

And it has been fixed by Alvaro here, included in 9.4.1:

So perhaps it was the problem they faced?
