Hello,
Thank you to Oleg for your help with this earlier! It resolved it very
nicely!
I still have one remaining issue which I can't figure out, perhaps best
explained with an example:
CREATE TABLE sometable (
title TEXT,
body TEXT,
footer TEXT,
all_fti TSVECTOR
);
UPDATE sometable SET all_fti = setweight(to_tsvector(title), 'A') ||
setweight(to_tsvector(body),'B') || setweight(to_tsvector(footer), 'C');
INSERT INTO sometable (title, body, footer) VALUES ('something in the
title', 'something in the body', 'something in the footer');
INSERT INTO sometable (title, body, footer) VALUES ('anything in the
title', 'anything in the body', 'anything in the footer');
INSERT INTO sometable (title, body, footer) VALUES ('whatever in the
title', 'whatever in the body', 'whatever in the footer');
.. What I can't figure out is how to make those last 3 inserts
automatically update all_fti via a trigger... The documentation would
show something like:
CREATE TRIGGER sometable_update_fti BEFORE UPDATE OR INSERT ON sometable
FOR EACH ROW EXECUTE PROCEDURE tsearch2(all_fti, title, body, footer);
.. but as expected, this does not take into account the result of the
"setweight" function.... Unfortunately, I am not very skilled with
Postgres's triggers (yet) and I can't find any documentation on how to go
about this...
Any thoughts?.....
