I know this is basic, but couldn\'t find and in a hurry to know the answer. When interfacing with PostgreSQL through PSQL, it appears that DML statements are auto-commited, that is, a change I make in one session is seen from another without 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 sorry for the newbie question.
