Waiting for 9.3 – JSON generation improvements.

On 10th of March, Andrew Dunstan committed patch:

JSON generation improvements.
 
This adds the following:
 
    json_agg(anyrecord) -> json
    to_json(any) -> json
    hstore_to_json(hstore) -> json (also used as a cast)
    hstore_to_json_loose(hstore) -> json
 
The last provides heuristic treatment of numbers and booleans.
 
Also, in json generation, if any non-builtin type has a cast to json,
that function is used instead of the type's output function.

Catalog version bumped.

Waiting for 9.2 – JSON

On 31st of January, Robert Haas committed patch:

Like the XML data type, we simply store JSON data as text, after checking
that it is valid.  More complex operations such as canonicalization and
comparison may come later, but this is enough for not.
 
There are a few open issues here, such as whether we should attempt to
detect UTF-8 surrogate pairs represented as \uXXXX\uYYYY, but this gets
the basic framework in place.

and then, 3 days later, Andrew Dunstan committed another one, related:

Also move the escape_json function from explain.c to json.c where it
seems to belong.
