No, libpq binary mode is not architecture-specific. I think you're thinking of on-disk binary compatibility. But libpq binary mode is just a binary network representation of the data instead of an ascii representation. It should be faster and more efficient but it still goes through binary input/output functions (which aren't named input/output) I actually wonder if having this would be a good way to get some code coverage of the binary input/output functions which I suspect is sadly lacking now. It wouldn't necessarily test that they're doing what they're supposed to... but at least they would be getting run which I don't think they are currently? -- greg
