I was thinking maybe "log_shipping" instead of "archive", since we're
conflating the technology (log shipping) with the technology used to
implement it (archiving or streaming).
Possible "crash_recovery" rather than just "crash" where you have "mimimal".
I don't love "hot_standby" either but it might be the least of evils.
