http://pgfoundry.org/projects/pgtune/ aims to provide a tool for 8.4,
that's working but still needs documentation and some loose ends cleaned
up. Its suggestions aren't good yet for Windows systems yet, that's the
biggest bug left in there.
That's aimed to automate the suggestions set out in
http://wiki.postgresql.org/wiki/Tuning_Your_PostgreSQL_Server
One day I'll make that work better with older versions too. It does
basically the right thing for 8.3 already but could be smarter, it
includes some parameters that aren't there in 8.2, and doesn't work at all
on 8.1 or earlier.
If you step outside of just free solutions, Enterprise DB's commercial
server product does more complicated autotuning via their DynaTune
feature.
