Yes. A transaction looks like this:
BEGIN;
SQL1;
SQL2;
COMMIT;
But it also looks like this:
SQL3;
because in PostgreSQL, everything is always automatically in a
transaction, and a bald SQL statement is just a transaction one
statement long. With autocommit off, I think what you get is no
COMMIT, but you still get the bald transaction.
What you really need is to make sure you're starting a
multi-statement transaction every time.
