Appending new data to existing field of Json data type

[VENKTESH GUTTEDAR <venkteshguttedar@xxxxxxxxx>]

Hello,

    As i am new to postgresql, i am learning through experimenting things.

    i have a table with json data type field, so there is some data for example :
       

        { [ { a:b, b:c } ] }

    and now if i append data then it should be like :

        { [ { a:b, b:c }, { e:f, g:h } ] }

    Is there any way to achieve this. please help.!

    I have Postgresql 9.3.5.
