Manipulating jsonb

Andreas,

take a look on https://github.com/erthalion/jsonbx. This is a place,
where all hstore functionality will be eventually ported. See this
table - https://gist.github.com/erthalion/10890778

Hello,

I'm playing with a 9.4 preview and the upcoming jsonb datatype. But
I'm missing the basic modification syntax.

Given the following situation:

CREATE TABLE test(key int, jsonval jsonb);
INSERT INTO test VALUES(1, '{"a": 1, "c": 3}');

How can I UPDATE that row with '{"b": 2, "d": 4}' ? Something like
this does not work:

UPDATE test SET jsonval = jsonval || '{"a": 1, "c": 3}'::jsonb
where key = 1;

The result should be

{"a": 1, "b": 2, "c": 3, "d": 4}

The same goes for removing values.

Did I overlook something obvious or is there really no way to do that right now?

Best regards,
Andreas Heiduk

Hello Oleg,

how are the odds that the '||' and '-' operators from jsonbx will be
included in the public 9.4 release?

No way, Andreas !

But, we hope, Dimitri will release his extension before 9.4, so
anybody could install it.

Hello Oleg,

that's a pitty. I think at least some server-side processing for jsonb
would make a round package. But I will monitor Dimitri's extension.

Thank you very much for your answer.
