The difference would be pretty marginal --- especially if you choose to use bigints instead of ints. (A timestamp is just a float8 or bigint under the hood, and is no more expensive to compare than those datatypes. Timestamps *are* expensive to convert for I/O, but comparison does not have to do that.) I wouldn't recommend kluging up your data schema just for that. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 3: 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
