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.
