You didn't say anything about how much memory you have, but you need to
be careful with *work_mem, as being too agressive can run the machine
out of memory.
I have 4Gb of memory and the machine is pretty much a devoted database
server. We use it mainly for data warehousing and mining; there are
rarely more than 2 active connections and never more than 5 total, so I
have felt pretty comfortable with leaving work_mem pretty generous. I
will likely have to change that if the machine becomes more active.
