Upgrading seems risky.  If you run into incompatibilities, will you be
able to revert?  I had the idea that some fairly fundamental Cobalt
services depend on their Postgres installation.

Coexistence, on the other hand, is trivial.  Just pick a different
installation prefix, data directory, and port number for the 7.3
installation.  For instance,
    configure --prefix=/usr/local/something --with-pgport=5433
