That's cool, but I don't have a Fedora or Ubuntu VM handy, and it does seem like if people are working on testing against old versions, they might even want to be able to recompile with debugging statements added or something. So I think actually compiling is a lot better than being able to get working binaries from someplace, even though the latter is better than nothing. > I'm not opposed to us cutting off support for very old versions, > although I think we should only do that very occasionally (no more than > once every five years, say) unless there's a very good reason.

Yeah, I think having a small number of buildfarm animals testing very old versions would be nice. Perhaps we can call them tyrannosaurus, brontosaurus, triceratops, etc. :-) -- Robert Haas EDB: http://www.enterprisedb.com
