Something else to consider is that this is made worse because tuning for
pgsql is quite different than tuning for something like Oracle or DB2,
which don't deal as much with metrics such as random access cost v.
sequential access. They also take the approach of 'give me as much
memory as you can; I'll take it from there, thankyouverymuch', which
makes effective_cache_size a bit of a mystery.
