Thread: How do I upgrade or coexist PostgreSQL on a Cobalt XTR system?

I have a Cobalt XTR system that uses PostgreSQL 7.0.2
and I would like to either upgrade to PostgreSQL 7.3.1
or install PostgreSQL 7.3.1 to co-exist on the same
system.  Does anyone have or know where I can find
instructions on how to do either of those options?
This apparently is not a simple upgrade, because the
Cobalt XTR relies on PostgreSQL to support some of its
functionality and I simply cannot just remove the
database and install the new one expecting the rest of
the system to function correctly.  There is at least
one Cobalt process called swatch that I know of that
relies on libpq.so.2.1 which PostgreSQL 7.3.1 upgrades
to libpq.so.3.0 and swatch does not want to use.

TIA.

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
