I would copy the data directory somewhere else for safe keeping leaving the original in place. Then reinstall Postgres, the install should leave the original directory alone and you will be ready to go. Should there be an oops you will have the copy as backup.

    Well that would make more sense of things.  I had removed and
    re-installed the postresql-common package:

    https://packages.debian.org/jessie/postgresql-common
    <https://packages.debian.org/jessie/postgresql-common>

    and thought that it would leave the main PG package in place.  But
    perhaps I was wrong.  I’ll follow Tom’s advice and just re-install
    everything (saving the old data directory) and hope the new
    installation can use the old data data directory.


If you removed it and then installed it, then the removal would remove
all dependent packages and if you then only intalled that one and not
the dependencies that would explain it.

If you had run a reinstall on it, then it would've kept them around.



    One question about this approach though:  the Debian package
    installation automatically initializes the new data directory and
    starts PG.  If I shut it down and copy the old data directory into
    the newly installed one, will there be an xlog issue?


You have to copy the xlog along with the database.

Or if you leave it in place where it is, the packages won't initialize
a new data directory.
