The sequences should have files, so I make it 452 pg_class rows that
should have corresponding files.  However, those rows that have
relisshared = 't' correspond to files in $PGDATA/global, not files
in your per-database directory.  In 7.2 I believe there should be ten
such rows, one of which is pg_xactlock, so 443 seems the correct count.

Could you make a list of the pg_class.relfilenode values for
'S','i','r','t' rows (excluding relisshared rows), and compare that
against what oid2name is reporting to see what it is missing or
getting wrong?
