Huh, curious, I think what I'm seeing is: on my development machine,
`File.exist?` returns true for symlinks, but, on our production
machine, `File.exist?` returns false for symlinks.
I imagine this is a difference in the implementation of the underlying
system calls? Curious!
This new check should work more reliably across platforms. I considered
checking both `exists?` and `symlink?`, but decided that, in the
unexpected case that `latest.sql.gz` exists but is an actual file
instead of a symlink like we expect, it's probably best to avoid
overwriting it anyway, and a crash on the `symlink` attempt is a
reasonable way to do that.
