I think it's kind of stetching the PostgreSQL documentation to be covering 
that.  It's hard to generalize here without giving a fair amount of 
background and caveats--that last message was about as compact a 
commentary on this as I could come up with.  One of the things I was 
hoping to push into the community documentation one day was a larger look 
at disk layout than covers this, RAID issues, and related topics (this got 
started at http://www.postgresql.org/docs/techdocs.64 but stalled).

What's nice about putting it into a web-only format is that it's easy to 
hyperlink heavily into the archives to recommend specific discussion 
threads of the issues for reference, which isn't practical in the manual.
