I tried doing a full reinstall of Ubuntu-17.10 followed by a postgresql
install from the bionic repo (instead of installing 10.1 per above and
trying to upgrade)

   # apt-get -qy install postgresql postgresql-client postgresql-contrib \
       postgresql-doc pgadmin3 postgresql-server-dev-10 libpq-dev

    Some packages could not be installed. This may mean that you have
   requested an impossible situation or if you are using the unstable
   distribution that some required packages have not yet been created
   or been moved out of Incoming.
   The following information may help to resolve the situation:

   The following packages have unmet dependencies:
    libpq-dev : Depends: libpq5 (= 10.3-1.pgdg18.04+1) but it is not going to be installed
    pgadmin3 : Depends: libgcrypt20 (>= 1.8.0) but 1.7.8-2ubuntu1 is to be installed
               Depends: libpq5 (>= 8.4~) but it is not going to be installed
               Recommends: pgagent but it is not going to be installed
    postgresql : Depends: postgresql-10 but it is not going to be installed
    postgresql-client : Depends: postgresql-client-10
    postgresql-contrib : Depends: postgresql-contrib-10

Is there any reason now not to conclude that the 10.3 bionic version is
simply incompatible with Ubuntu-17.10 (at least without a lot more package
wrangling chops than I have)?

One can install postgresql-10.1 but one cannot upgrade it to get security
fixes or to be able to load data dumped from another 10.3 database.

Given that Ubuntu-18.04 will be out soon I guess this is pretty much moot
except for a few unfortunates like me who absolutely need 10.3 but have no
option to upgrade.  I guess the lesson is that running the Pgdg versions
of Postgresql on any but the LTS versions of Ubuntu is pretty risky.
Live and learn.  Maybe this will help someone else.
