Curiously enough, ANSI doesn't define an INTERVAL-divided-by-INTERVAL
function either. Also, it rather looks like ANSI adopted the position
Peter E. expressed:
Year-month intervals are mutually comparable only with other year- month intervals. [...]
Day-timeintervals are mutually comparable only with other day- time intervals. [...] Operations involving
itemsof type datetime require that the date- time items be mutually comparable. Operations involving items of
type interval require that the interval items be mutually compara- ble.
