There was once a grand experiment in support autocommit = off on the
server side. After the fires were put out, it was decided to leave it in
userland.

the standard way of "turning off" autocommit is to issue a begin; before
you do anything. Then, should all go well you can commit; or rollback;
should things go horribly wrong. should an error occur, Postgresql will
rollback automagically when you try to commit.

begin;
insert 1000 rows;
commit;
