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.... -- Michael Fuhr http://www.fuhr.org/~mfuhr/ ---------------------------(end of broadcast)--------------------------- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
