Is that how it works for an index as well? I just found out that I have
  an index that is 35GB, and the table is 85GB.  ( I will look into the
index, it works fine, but an index that is almost one third of the size
of the table, seems a little bit strange. )
So if it works the same way and the index uses a B-tree, I assume it
only loads the pages that contains the subpart of the index that are
relevant, is this correct?
