thanks for the link. That's great news.
We've managed to install PG 8.0.0 dev3 on Win2k yesterday. After checking out HEAD with the changes from Jeff there was a small issues with timezones, but we could source the SQL manually. The PG installer is great, just make sure to enter different passwords for the postgres Win2k user and the postgres database user...
Concerning the "unified installer": The Postgres 8.0 installer already contains the creation of a new Win2k user ("postgres"), hierarchical installation options (PG, doc, ODBC drivers, etc) and some sanity checks. So maybe it could be actually easier to start with the PG installer and add code to create an additional "aolserver" user and to extract the AOLServer and OpenACS files into some directories. I understand that the main complexity of your installer is really to put together all these modules, right?
What's missing then for us is loading a database dump into PG and to start a browser on the right host/port because "non sophisticated users" want to see results immeditately. So we would include a sample "company configuration" as a DB dump with a lot of predefined users, customers, prices, projects, forum discussions and a special home page that would let the user log in as one of several demo users. Checkout http://ptdemo.dnsalias.com/ for an example of what I mean.
What development environment do you use to compile your installer? Is it just M$ Dev Studio?
