Looks like someone or something changed the permissions on the

I've had a look at this file, and postgres has "Full Control".

Further, the system works fine normally. The permissions error appears
to be an isolated error. Is it possible that this error means something
else?

Are there likely to be serious integrety implications if Postgres failed
to access/write to this table for whatever reason, or would the
transaction be rolled back.   

Previous reports of this type of intermittent behavior on Windows have been 
traced back to AV software. 
 

The server does run NOD32 AV but it is switched off for the data directory. Is there a possibility that file system errors can be reported if there is a heavy load on the file system? The server also runs as a file server.
