Don't use [u]int64 because that does not necessarily match these format specs. It's probably physically compatible, but that won't stop pickier compilers from nagging about a format mismatch. But what I thought Michael was griping about is the use of "int", which is a noise word here. Either "long long int" or "long long" will work, but I think we've preferred the latter because shorter. regards, tom lane
