Sorry, I've messed things for myself.

Ok. In short, I vote for UNIQUE_ID (unrelated to pg_class.oid) file names.
I think that it's better to implement this (but neither OID nor OID.VERSION)
right now
because of this is like what we'll have in new smgr -
tablespace_id.relation_file_node.
Pg_class' OID is kind of logical things, totaly unrelated to the issue
how/where to
store relation file.

Please comment ASAP.

Philip Warner mentioned about the advantage of random number.
It's exactly what I've wanted to say.

It is preferable that file naming rule is encapsulated so that we
can change it without notice.
