Обсуждение: Set autocommit to off
Does somebody knows why the Postgresql 7.4.8 or later doesn't supports the option "SET AUTOCOMMIT TO OFF"? Thanks.

See this message: http://archives.postgresql.org/pgsql-general/2005-07/msg00064.php In short, server-side autocommit is not possible after 7.3, I think. Instead, use a transaction block (BEGIN...COMMIT) or set it on the client side like this in psql: http://www.postgresql.org/docs/8.0/interactive/app-psql.html and search for autocommit. Hope that helps.... Sean

Because server-side autocommit was a bad idea. See the 7.4 Release Notes. http://www.postgresql.org/docs/7.4/static/release-7-4.html "The server-side autocommit setting was removed and reimplemented in client applications and languages. Server-side autocommit was causing too many problems with languages and applications that wanted to control their own autocommit behavior, so autocommit was removed from the server and added to individual client APIs as appropriate." -- Michael Fuhr

I had to install Dspace release 1.3.1 (http://sourceforge.net/projects/dspace/) and during the installation process I have had an error "SET AUTOCOMMIT TO OFF is no longer supported" at Postgresql-7.4.8 and Postgresql-8.0.3. So I installed Postgres-7.3.10 and everything worked well. Thanks for your attention.
