Обсуждение: Typo in online docs

On this page:http://www.postgresql.org/docs/8.4/interactive/explicit-locking.html

This chapter:13.3.4. Advisory Locks

This example:SELECT pg_advisory_lock(id) FROM foo WHERE id = 12345; -- okSELECT pg_advisory_lock(id) FROM foo WHERE id
>12345 LIMIT 100; -- danger!SELECT pg_advisory_lock(q.id) FROM(  SELECT id FROM foo WHERE id > 12345 LIMIT 100;) q; --
ok

Last statement seems bogus to me ...
