Tom,
To get around the non-UTF8 chars I used following function :
CREATE OR REPLACE FUNCTION u_messageblk_idxfti() RETURNS "trigger"
AS $$
DECLARE
BEGIN
RAISE NOTICE '[DBMAIL] Trying ID %', NEW.messageblk_idnr;
BEGIN
NEW.idxFTI := to_tsvector('simple', encode($x$E$x$||
NEW.messageblk, 'escape'));
RAISE NOTICE '[DBMAIL] Ended ID %', NEW.messageblk_idnr;
RETURN NEW;
EXCEPTION
WHEN character_not_in_repertoire THEN
RAISE WARNING '[DBMAIL] character_not_in_repertoire ID %',
NEW.messageblk_idnr;
NEW.idxFTI := to_tsvector('simple',
'character_not_in_repertoire: This email contains illegal
characters.');
RETURN NEW;
END;
END;
$$
LANGUAGE plpgsql;
Hope this helps others with DBmail and tsearch2 on postgres 8.2
Thanks for your help Tom,
ilan
