Hi Adrian,

The JSON value is inserted into a column in the database which I can see. 
But the trigger which has to convert this JSON value in not tsvector column is not updating that column.

regards

Well, the obvious comment on that is "that JSON value hasn't got any qtext
field".  So the ->> operator is returning null, the coalesce() is
replacing that with an empty string, and you end up with an empty
tsvector column.
