Postgres: How to convert a json string to text?

Question

Json value may consist of a string value. eg.:

     to_json
-----------------
 \"Some \\\"text\\\"\"

In 9.4.4 using the #>> operator works for me:

select to_json('test'::text) #>> '{}';

To use with a table column:

select jsoncol #>> '{}' from mytable;
