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
