Indeed, and I would argue that your proposed change is exactly wrong. For instance, SELECT * FROM foo WHERE col > 4; SELECT * FROM foo WHERE col > 5; Under READ COMMITTED, the second SELECT may retrieve rows not found by the first, which would be impossible under SERIALIZABLE mode. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 1: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
