could not open relation - why?

Hello,

within my log there is the following snippet:

2006-08-07 13:20:27 LOG:  autovacuum: processing database "template1"
2006-08-07 13:20:47 ERROR:  could not open relation with OID 311438
2006-08-07 13:21:52 LOG:  autovacuum: processing database "postgres"

now there are a number of possibilites, why PostgreSQL could not open:

a) the file is gone
b) no access priv
c) file is open locked for single use
d) ???

Is there any way I can get more detailed information, why this happened?

Harald
