Re: PostgreSQL calibration

Are there really any performance settings of much interest beyond the
shared and non-shared memory settings? Beyond those the interactions

certain options like fsync = false should never be 'recommended'.

On the other hand, a way of empirically deriving some 'correct'
optimizer parameters for a given machine would be very nice :-)
