This test is 100% faulty, because it fails to consider the fact that the accumulator used by sum() isn't necessarily the same type as the input data. In fact we sum ints in a bigint and bigints in a numeric to avoid overflow. If you try it with max() you'd likely get less-surprising answers. 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
