Hi,

Just a quickie - I heard that linux does not have a working fsync() call
(it has no concept of raw devices).  In other words, fsync cannot be used
to ensure that data is on disk (try it with a floppy - it returns IMMEDIATELY!!! - long before the write finishes)

This is for ALL linuxes.

Does this mean that postgres is unrealiable (or non ACID-conforming) under linux?

Gary
