And here's an even smaller one that doesn't involve plpython.
create or replace function upd() returns trigger language plpgsql as
$$
declare
rec record;
begin
new.description = 'updated in trigger';
return new;
end;
$$;
create table onetest (
id int,
filler text,
description text
);
create trigger onetest_t before update on onetest for each row
execute procedure upd();
insert into onetest select a, repeat('xyzxz', 100), 'new' from generate_series(1, 50) a;
BEGIN;
SET transaction isolation level SERIALIZABLE;
UPDATE onetest SET description = 'no no', id = 1 where id = 1;
commit;
