That sounds somewhat interesting, and I understand the crontab approach,
but the key to your methods is that "last action" thing. I can see how I
might get a date from some table that has an column value that gets
assigned the current date after insert or update (using DEFAULT or a
trigger), but what if the user's access is read-only, i.e., they perform
only SELECT operations? How could I catch that?
