That nickel would be yours to keep :)

'public.ct_com_board_message'::regclass and attname = 'idxfti';

Concerning the table definition - sorry, I edited out a couple of fields too
many, which I assumed were not relevant to this case. Here is the full table
definition:
CREATE TABLE public.ct_com_board_message
(
board_id integer DEFAULT 0,
thread_id integer DEFAULT 0,
father_id integer DEFAULT 0,
message_id integer NOT NULL DEFAULT 0,
user_id integer DEFAULT 0,
title text,
signature text,
follow_up text,
count_reply integer DEFAULT 0,
last_reply timestamptz,
created timestamptz DEFAULT now(),
article_id integer DEFAULT 0,
logged_ip text,
state_id smallint DEFAULT 0,
user_login text,
user_status smallint DEFAULT 5,
user_rights text,
text text,
deleted_user_id integer DEFAULT -1,
user_rank text,
user_rank_description text,
user_rank_picture text,
deleted_date timestamptz,
deleted_login text,
user_created timestamptz,
poll_id integer DEFAULT 0,
last_updated timestamptz DEFAULT now(),
idxfti tsvector,
CONSTRAINT "pk_ct_com_board_message" PRIMARY KEY (message_id)
);
The trigger definition:
CREATE TRIGGER "tsvectorupdate"
BEFORE
INSERT OR UPDATE
ON "public"."ct_com_board_message"
FOR EACH ROW
EXECUTE PROCEDURE
pg_catalog.tsvector_update_trigger(idxfti,'pg_catalog.german',title,text,user_login);
And the error message from the log:
<2008-04-09 13:42:48 CEST - 8820: 192.168.222.132(52319)@community>ERROR:

<2008-04-09 13:42:48 CEST - 8820: 192.168.222.132(52319)@community>STATEMENT:

, MESSAGE_ID
, USER_ID
, TITLE
, TEXT
, SIGNATURE
, LOGGED_IP
, USER_LOGIN
, USER_STATUS
, USER_RIGHTS
, USER_CREATED
, LAST_REPLY
)
values
(
1
, 6579073
, 0
, 6579073
, 39
, 'Test TSearch2 tsvector_update_trigger'
, 'tsvector_update_trigger test test test'
, ''

, 'Markus_Wollny'
, 100
, 'yp'
, '2001-03-22 16:54:53.0'
, CURRENT_TIMESTAMP
)
Now I have a custom trigger function:
CREATE or REPLACE FUNCTION "public"."board_message_trigger"()
RETURNS "pg_catalog"."trigger" AS
$BODY$
begin
new.idxfti :=
to_tsvector(coalesce(new.title,'')) ||
to_tsvector(coalesce(new.text,'')) ||
to_tsvector(coalesce(new.user_login,''));
return new;
end
$BODY$
LANGUAGE 'plpgsql' VOLATILE;
And this trigger:
CREATE TRIGGER tsvectorupdate
BEFORE INSERT OR UPDATE ON ct_com_board_message
FOR EACH ROW EXECUTE PROCEDURE board_message_trigger();
Everything works fine. It's sort of less elegant though than having just the
one generic trigger function and configuring the needed fields in the trigger
itself.
Kind regards
