There is project on gborg(or somewhere else), written as deamon that
monitors server and calculates the best configuration based not only on
platform, but also on server load.(damn, I can't remember the project
name!). I think that monitoring is done using pg_stat.
If group think that this is important isue, we can try to do something like
this, or even include that project in contrib ? I know that I did downlad
the source, but never tried if it works.
Maybe I can try it I let You know ? Even beter if author is reading this
list !
Regards !
