For tcl, postgres, aolserver, linux etc. specific questions, it seems other sites specializing in those specific technologies best address them. For example, the most obvious place to find answers to linux security issues is to discuss it at linux-centric websites. OpenACS needs to focus on it's own technology and how it integrates with other technology. With that it mind...
Philip Greenspun has identified my current problem: "PostgreSQL and OpenACS 4.x. Learners always get stuck on the trivial stuff, e.g., finding the error log in the file system, rather than the slightly deeper stuff, e.g., interpreting the contents of that error log."(Greenspun).
How does the OpenACS installation architecture differ between Oracle and Postgres installations?
More specifically, Where is the openACS installation architecture described for a postgreSQL-OpenACS4.x installation?
For the record, I have been RTFMing at https://openacs.org/doc/architecture-install.html and https://openacs.org/doc/installation.html documents as well as the others listed in this thread and other threads/forums... and references to 4.x documentation at the bottom of the 3.x docs at https://openacs.org/doc
