Man, it's not that easy. :-) Mainly because you will need some database
activity. For example, work_mem, checkpoint_segments, and
checkpoint_timeout depends on the database's dynamic.
Database are not that static so another idea is to build a piece of
software that monitors the database and do the modifications based on
some observations (log, stats, etc). Don't forget that some of these
options need a restart. So maybe your tool just advise the DBA that
he/she could change option X to Y.
Such a tool was proposed later [1] but it's not up to date. :(
