Couldn't you simply tell postgres to put it's socket in, say, /var/run, and create a symlink to that socket in the
global/tmp directory?

If we're going to have this at all, we should go all the way and support an arbitrary number of sockets. But then, is
thereany advantage in providing this feature natively compare to simply creating symlinks?
