Even if the client doesn't want to store it in a separate table, it's
going to be worthwhile, since you can use the table for other kinds of
logging and the persistence issue Otto mentions.
things otherwise not seen in the Apache logs, it would be great to have
things work for even situations such as this too, which could be helped
out by having a post_id column in addition to a unique event name....
