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?
