* This is the INSERT query, called from PHP/Apache
INSERT INTO log_event (user_id, ip, action_id, object1_id, object2_id,
event_timestamp)
VALUES ($1, $2, $3, $4, $5, NOW())
So the timestamp is generated by NOW(), and the pkey is generated by using
the default value (nextval).
* There are no UPDATE queries.
* There a few DELETE queries that are lauched daily (called from PHP/cron)
DELETE FROM log_event WHERE action_id = $1 AND event_timestamp < NOW() - '1
month'::interval
(some events are not worthy of archiving individually, we just keep totals)
