Yes,I know it.
But I'm now inclined to generate unique relation file name each time
in order to have different file names for different versions of a same
relation oid.  Without chainging relation oids,we would be to do 
nothing about their attributes/constraints etc.

Anyway this must be decided after sufficient discussion.
It's not the time to do it now.
