Problem with PL/pgSQL in 7.03

Hi
I migrated from version 6.5 to 7.03
My function (see below) doesn't work in 7.03, but it works in 6.5 .

CREATE FUNCTION "projects_update_function" ( ) RETURNS opaque AS '
begin
if TG_OP=''UPDATE'' then
NEW."Last Modify":=''now'';
return NEW;
end if;
end;
' LANGUAGE 'plpgsql';

CREATE TRIGGER "Projects_Update" BEFORE UPDATE ON "Projects"
FOR EACH ROW EXECUTE PROCEDURE "projects_гpdate_function" ();

NOTICE: plpgsql: ERROR during compile of projects_update_function near line 2
ERROR: unterminated "
