Committed with the following small changes:

* I renamed the new option to --missing-stats-only, which I felt was more
  descriptive.

* I moved the new tests to the main vacuumdb test file and interspersed
  some --analyze-only uses.

* I fixed a couple of other things in the new parts of the catalog query
  that were not fully qualified.
