Hi there,
Im having a go at writing my first set of triggers for postgres and Im
having trouble with an error message which the trigger produces when it
tries to compile/call the function Ive written in pgsql. The error message
is:

ERROR:  syntax error at or near ";"
CONTEXT:  compile of PL/pgSQL function "text_update" near line 31

I cant find the error! As far as I can see the syntax is fine from whats in
the manual. Can anyone see what the problem with the function below is:


CREATE FUNCTION text_update() RETURNS TRIGGER AS'
DECLARE
allText TEXT;
currentRecord RECORD;
BEGIN
IF TG_WHEN = BEFORE THEN
	RAISE EXCEPTION ''Trigger function text_update should not be called before
INSERT/UPDATE/DELETE'';
END IF;
IF TG_LEVEL = STATEMENT THEN
	RAISE EXCEPTION ''Trigger function text_update should be called as a row
level trigger'';
END IF;
IF TG_OP = DELETE THEN
	DELETE FROM cks_messagetext WHERE cks_messagetext.id = OLD.id;
	RETURN OLD;
ELSIF TG_OP = UPDATE THEN
	FOR currentRecord IN SELECT textdata FROM cks_part WHERE cks_part.type = 1
AND
	cks_part.sourcemessageid = NEW.id LOOP
		allText := allText || '' '' || currentRecord.textdata;
	END LOOP;
	allText := allText || '' '' || NEW.subject;
	UPDATE cks_messagetext SET cks_messagetext.textdata = allText WHERE
cks_messagetext.id = NEW.id;
	RETURN NEW;
ELSIF TG_OP = INSERT THEN
	FOR currentRecord IN SELECT textdata FROM cks_part WHERE cks_part.type = 1
AND
	cks_part.sourcemessageid = NEW.id LOOP
		allText := allText || '' '' || currentRecord.textdata;
	END LOOP;
	allText := allText || '' '' || NEW.subject;
	INSERT INTO cks_messagetext (id, textdata) VALUES (NEW.id, allText);
	RETURN NEW;
ENDIF;
END;
'LANGUAGE plpgsql;


Thank you for any help in advance.
