Seems that oid file names will fix this...
Currently, each shared buffer description structure has
database/table names for the purposes of "blind" writes
(when backend cache hasn't entry for relation and so
bufmgr can't use cache to get names from oids).
ALTER TABLE ... RENAME renames relation file(s) but doesn't
change relation name inside shbuffers...
