Agreed. I have updated the warning to say "missing or inaccessible
sequence on publisher", so it covers both cases where the sequence is
actually missing and cases where the publisher-side role cannot access
its sequence data.

I also renamed the related variables from missing_* to unavailable_*,
and updated the associated comments and DEBUG message to avoid implying
that the sequence is necessarily absent on the publisher.

The TAP expectations for both the dropped-sequence case and the
insufficient-privileges case have been updated to match the new wording.

Attached is v5 with these changes.

Thoughts?

Ayush
