Some questions to clarify this:
- What settings do "newbies" (or anyone else) typically need to change?
Please post a list.
- What values would you set those settings to? Please provide a description
for arriving at a value, which can later be transformed into code. Note that
in some cases, not even the documentation provides more than handwaving help.
- If we know better values, why don't we set them by default?
Another orthogonal stumbling block on the way to making all of this automatic
is that the surely criticial shared_buffers setting will in any useful
configuration require messing around with kernel settings that no PostgreSQL
tool can really help with.
