AW: [HACKERS] Plans for solving the VACUUM problem

> Would it be possible to split the WAL traffic into two sets of files,

Sure, downside is two fsyncs :-( When I first suggested physical log 
I had a separate file in mind, but that is imho only a small issue.

Of course people with more than 3 disks could benefit from a split.

Tom: If your ratio of physical pages vs WAL records is so bad, the config
should simply be changes to do fewer checkpoints (say every 20 min like a 
typical Informix setup).
