Hello,

I ran a simple test... I ran defrag on my drives. Then I initialized 
pgbench with a -s 1000.

11% fragmentation. I dropped the bench database, and my fragmentation is 1%.

I know this isn't *our* fault :) but I am curious if there is anything 
we can do about the way postgresql writes files to help limit fragmentation.

Essentially, this makes win32 impossible in a 24x7 environment (jokes 
aside about Win32 in general) because we *have* to defrag on Windows and
Windows won't defrag open files (thus anything PostgreSQL is using).

Sincerely,

Joshua D. Drake
