We've never actually enforced that AFAIK, so this might be considered a
documentation bug.

You could argue that the problem there is that LookupTypeName is not
verifying that what it finds is really an array of the specified type.
We could make it look up the given name without modification and then
apply get_array_type(), but this would mean two catalog lookups not one.
Still, that might be better than possibly breaking applications that
have historically worked.
