  This information is not stored in any way that aptitude can get at it,
so no, you can't find this out.  In fact, I don't believe there's any
tool that can do this, because the information isn't published in a
machine-readable form anywhere (please correct me if I'm wrong).

  You could maybe search for packages that replace or conflict with your
obsolete package, but that's a scattershoot approach, at best.
