    Up to now we kept the storage manager overhead in the system.
    Actually there is no way to tell which storage manager to use
    for a particular table/index, so anything goes to the default
    which is the magnetic disk one that  uses  single  files  for
    each relation.

    There   was  a  discussion  about  simplifying  it,  but  the
    consensus was to let it as is because it is the  base  for  a
    tablespace and/or raw device manager.

    AFAIK,  noone  is  working  on  it,  so it must be really FAR
    future. But the plan is still alive.
