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.
As Tom explained, in your trigger function you have:
to_tsvector('swedish',coalesce(New.body->>'qtext','')::text);
In the body JSON you are passing in:
$4 = '{"name": "Do you like Pizza ?", "type": "cat", "store":
[{"labeltext": "Yes", "labelvalue": 1}, {"labeltext": "No",
"labelvalue": 2}, {"labeltext": "Other", "labelvalue": 3}, {"labeltext":
"Don''t know", "labelvalue": 4}], "target": {"place": "Sweden"},
"askfreq": "once", "whydesc": "Because I like it :)"}'
there is not 'qtext', so New.body->>'qtext' is getting you NULL which
the COALESCE is turning into '' which is making weighted_tsv look empty.
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.
