The PostgreSQL 8.3 one-click installers, and the 60 or so add-on
installers that are available through StackBuilder are the first of
our 'next generation' installers. The current version of Postgres Plus
Standard server (8.3) uses Apple's installer on Mac, Wix on Windows
and some Java thing on Linux. The current version Postgres Plus
Advanced Server (8.3R2) uses a java based Installshield installer.
The next version of Postgres Plus Standard Server (which will probably
be out in late Q3/Q4) will use the same technology as we're using for
PostgreSQL on all platforms. It will reuse a fair chunk of the
existing installers code, and was intentionally designed that way to
optimise the use of resources.
The next version of Advanced Server (no idea on the ETA of that) will
almost certainly use the same technology, but with significantly less
shared code, mainly because the products are quite different.
So currently, all of those resources have been dedicated purely to
PostgreSQL, but it is true that we will benefit from reduced/combined
testing requirements on Postgres Plus in the future.
