I don't think you heard a word I said :-( You appear to be adding a whole lot of platform dependency (passing FDs around other than by fork() is not portable) in return for loss of functionality (applications can't rely on session state anymore) and highly dubious performance gain (just because a backend has started does not mean it's built up a reasonable working set of cache entries; you can't expect that firing off a new backend for every transaction is going to be anything but a huge performance loss, even if you assume its visible session state is exactly what the application needs). Also it sounds to me like the postmaster will now become a performance bottleneck, since it will need to be involved in every transaction start. You're welcome to pursue this if you like, but I'll bet lunch that you are wasting your time. regards, tom lane
