Why do we have either sigsetjmp or setup_cancel_handler inside the per-line loop, rather than just before it? There is a lot of stuff in MainLoop that doesn't seem like it really needs to be done on every single line, particularly not the repeated fetching of psql variables that couldn't possibly change except inside HandleSlashCmds. But that all ought to be the same on Unix or Windows. regards, tom lane
