inventory / db01: increase memory and cpus and adjust postgresql settings
    
    GIve db01 64gb mem and 24cpus. We have them on that virthost and this
    host is one of our busiest.
    
    Adjust the postgresql params based on what I now know from adjusting
    db-koji01. This should hopefully improve a number of applications
    performance.
    
    Note that we need a restart/reboot to have the cpu changes and postgres
    changes take effect. The memory change is already live.
