I think it would be an enourmous help for beginners if they had a "simple"
tuning tool which would tell them which values where altered (and possibly
why) from Postgres' default settings based on some basic information.
Like:
- machine hardware (disk layout, OS, installed memory, etc.)
- application usage (no. of clients, read/write activity, etc)

I don't think that such a tool could tune the database perfectly (or even very
good), but at least people new to Postgres would know where to start looking
for tuning it to their needs.

And I am not speaking about end users running an application that uses
Postgres. I talk about application developers like me that port their
application to use Postgres.
