Hi Micheal,
Thanks for the reply. I am using postgres 7.4.5 client. There's one that is using 7.4.1 client. I'm not sure if there would be any difference.
When i use psql and check the status of autocommit, it is set to enable. I'm not sure if libpq and psql uses the same defaults.
Thanks,
Hasnul

I am just wondering, by default, autocommit is enabled for every client
connection. The documentations states that we have to use BEGIN
and END or COMMIT so to increase performance by not using autocommit.
My question is, when we use the BEGIN and END statements, is autocommit
unset/disabled automatically or we have to disable/unset it manually?
What version of PostgreSQL is your server running and what client
software are you using? PostgreSQL 7.3 had a server-side autocommit
setting, but it caused problems with some clients so 7.4 got rid
of it and left autocommit up to the client. How to enable or disable
client-side autocommit depends on the client software, but if you're
able to execute a BEGIN (or START TRANSACTION) statement then you
should be inside a transaction until you execute COMMIT (or END)
or ROLLBACK. That is, unless your client intercepts these statements
and does whatever it wants....
