JSON is a data type:
http://www.postgresql.org/docs/devel/static/datatype-json.html
So what you need to do is at least to create a table with a column having as data type JSON, and then insert data into it:
=# CREATE TABLE json_tab (data json);
CREATE TABLE
=# INSERT INTO json_tab VALUES ('{"key":"value","key2":"value2"}');
INSERT 0 1
=# select * from json_tab ;
              data              
---------------------------------
 {"key":"value","key2":"value2"}
(1 row)
