throughPSQL, it appears that DML statements are auto-commited, that is, a change I make in one session is seen from
anotherwithout the original session issueing a COMMIT. Is this a result of PSQL interface and if so, can it be turned
off. Is PostgreSQL transactional in the sense that I can issue several DMLs and then ROLLBACK. If so, how. Thanks and
sorryfor the newbie question.
