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?
