Re: Некорректное пояснение к примеру в разделе 13.2.1 - Mailing list pgsql-docs

Hello,

First of all, this english language forum.
For questions in Russian you can use pgsql-ru-general@lists.postgresql.org list or may be postgres.ru site.

As for your question.

BEGIN; 

UPDATE website SET hits = hits + 1; 

DELETE FROM website WHERE hits = 10; 

COMMIT;

In this example you forget a main part.
DELETE statement must be run in a second session, after UPDATE in first session, but before COMMIT.

Look carefully in a documentation:

BEGIN;
UPDATE website SET hits = hits + 1;
-- run from another session:  DELETE FROM website WHERE hits = 10;
COMMIT;

So, example is correct.
