Обсуждение: json data type

Hi,

A project  in which i'm involved, make use of json data type for storing
some data sets. I have read that there is some work in progress to
implement json datatype support in postgres. So my question is; when and
in which version of postgres we can expect this implementation?

Thanks,
atu

I actually store a pretty good amount of JSON serialized data for my
website, kitchenpc.com which uses Postgres 9.0.  I don't have any
problems with this, I just use a text data type.  I'd be interested in
knowing what functionality would come with a JSON data type, like
could you query for all rows with an X property of > 5 or something,
eg {Y: 1, X: 6}

Yes, as far as i know, you can make queries on json content

There's been discussion of a couple of different patches on
pgsql-hackers in the past few months --- see the archives if you want
details.  AFAICT there's not yet consensus on which way to proceed.
So while it's possible there will be something of the sort in 9.1,
I wouldn't bet on it.

As was mentioned, there's nothing stopping you from storing JSON stuff
as text right now.  If you have any thoughts on what you would need
expanded JSON support to actually *do*, feel free to comment in the
pgsql-hackers threads.
