Yes, that seems doable. My point is that I've intentionally chosen to preload the libraries at the moment so that it's possible to define PGC_POSTMASTER GUCs and to use RegisterBackgroundWorker(). If we think that switching archive modules without restarting is more important, I believe we will need to take on a few restrictions. Nathan
