I'd expect it to throw an error that the tables are missing. I ran into
this today. All it really requires is that the view definition be
parsed at use time rather than at creation time.

As you say, functions are compiled at use time, and hence don't suffer
this problem. You can build a view on the function and it should be
transparent...

Have a nice day,
