If you use serializable mode for updating transactions, you must expect this error and deal with it (by retrying the transaction from the top). This is discussed in the documentation, eg at http://www.ca.postgresql.org/users-lounge/docs/7.3/postgres/transaction-iso.html#XACT-SERIALIZABLE You might also find it useful to go through the slides from this talk: http://conferences.oreillynet.com/cs/os2002/view/e_sess/2681 regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]
