Bit of a strange topic to find on a site about postgresql.. but mysql has some strange ideas.
I found
a mysql blog that details a rather strange bug.
Some queries are not logged into the system log.
I'm not really sure why but the poster doesn't seem to think it's a critical bug!?
If you want to see what queries are running against your database, you'd think the system log would capture everything.
I wonder if it could be modified to actually insert data using an 'insert into select' query..
