I can't really argue one way or another because *I* am
not likely to be able to offer an actual patch. At any
rate all I am interested in is that pg_upgrade does not
fail to upgrade in surprising ways.

Regarding restoring a pg_dump IMO the line would need to
be drawn along the -c/--clean option because using such seems
to clearly say that, yes, the user *wants* data to be deleted.

If -C/--create is used it shouldn't matter ...

However, I'm not saying that this is how it is to
be done. I am well aware that drawing such subtle
distinctions is walking quite a fine line.
