We are trying to perform a 'reindex database' and it will fail at varying points with a message like:
    ERROR:  could not open relation with OID 587495058
                                           or
    ERROR:  could not open relation with OID 587603875
 
When we queried pg_class we got no rows returned:
select oid,* from pg_class where oid in (587603875, 587495058);
 oid | relname | relnamespace | reltype | relowner | relam | relfilenode | reltablespace | relpages | reltuples | reltoastrelid | reltoastidxid | relhasindex | relisshared | relkind | relnatts | relchecks | reltriggers | relukeys | relfkeys | relrefs | relhasoids | relhaspkey | relhasrules | relhassubclass | relacl

There were no reindex processes running in pg_stat_activity and stopping/restarting postgres did not clear up these entries.
 
What could be causing these errors?
