currently, we bundle the postgresql.jar with our applications, and we
don't know what combination of systems it might end up being run on ...
the same package might land on solaris or AIX or Linux or even MS
Windows, and it might be run with anything from Java 1.5 or newer. The
postgresql server might be 8.3, 8.4, 9.x. as most of our deployments
end up deep in our Asian factories, the development group has little
control over the final runtime environment, and quite often new releases
of our packages are installed as application upgrades on existing
infrastructure hardware.
