Getting a unique document from multiple rows coming from postgresql is not that easy... The external tools considers each postgresql JSON fields as strings or have to parse it again. Parsing them would add an overhead on the external tool, and I d'say this would be better to build the entire JSON in the external tool. This leads not to use postgresql JSON builder at all, and delegate this job to a tool that is able to deal with > 1GO documents.

That's nice to hear. > Will this 1GO restriction is supposed to increase in a near future ?
Not planned, no. Thing is, that's the limit for a field in general, not just JSON; changing it would be a fairly large patch. It's desireable, but AFAIK nobody is working on it.
