This is all quite true of water, its not compressable.  Is water unique in
that aspect?

incorrect my friend.  if water was not compressable at all there would be no
pressure difference from the top to the bottom.  Admittedly it is not very easy
to do it, but it will compress. Most solids are compressable too. At hight
pressures, most things will fill a smaller volume.
