Mario,
This sounds nice, but I've read a lot of postgres documents and still do not
know how to disable autocommit. Is this possible? And how?
Yes, you can disable autocommit.  All you have to do is wrap your SQL statements within an explicit BEGIN ... COMMIT block.

Regards, Joe

Hi!

Thanks for the answer, but that's not disabling autocommit, it committing by
hand. What I mean ist Oracle-behaviour --> everthing is a transaction and
must be commited by "COMMIT". What I ment was something like "SET autocommit
to OFF" or something like this.

Anyway, thanks for your answer, now I know it's not possible.

Ciao,
         Mario

I'm sorry Joe but I must know.. What exactly does a "Knowledge Engineer" do?
I've never run into a person with that title before.. Perhaps it's because I
live in my office but I'm still curious..

Thanks!

Everything _is_ a transaction - the BEGIN ... COMMIT is implied, if you
don't wrap your SQL statements in BEGIN ... COMMIT.

Compare:

dominic=# INSERT INTO pages ( page_from, page_to, page_data ) VALUES ( 'Dominic', '555-1212', 'This is a test page');
INSERT 945129 1

[ This was one transaction ]
dominic=# SELECT count(*) FROM pages;
 count
-------
     1
(1 row)

[ This was the second transaction ]

... for a total of two transactions, as opposed to:

dominic=# BEGIN;
BEGIN
dominic=# INSERT INTO pages ( page_from, page_to, page_data ) VALUES ( 'Dominic', '555-1212', 'Test page number two.'
);
INSERT 945130 1
dominic=# SELECT count(*) FROM pages;
 count
-------
     2
(1 row)

dominic=# COMMIT;
COMMIT

[ This was just _one_ transaction ]

Hi Mitch,

PMFJI ... Knowledge Engineering is where Great Bridge touches its
customers- it encompasses engineering support, consulting, and
training.  Joe and his colleagues support our paying customers and also
do some development and documentation work.  And of course, they're on
the project mailing lists like everyone else :-)

<propaganda>
We made up the name to highlight what we think is important in an open
source company - real engineers, who deal in knowledge of the software.
So it's not some entry-level operator taking a customer's call, it's
someone who's a trained user of PostgreSQL himself.  Our competitive
advantage as a company can't lie in anything like proprietary software
products- it has to be in the people we hire and retain.
</propaganda>

Regards,
Ned
