The old code required the dump file to be version 2, but the new code
promises to
process version 1-3. Before this change is accepted, we need to test
that current
code can import a version 1 dump file. I am not sure it can.

When I implemented version 2, I kept the code backwards compatible in
that it could
continue to process binary files of the preceding version. But I don't
recall
ensuring that restore can handle both dump formats.

Note that incompatibility of dump format does not preclude upgrading. To
upgrade,
one can simply use the new version of the code to run dump on a version
1 binary file.
The dump is then in the current version. Upon restore, the binary file
will be marked
with the new version.
