Hi folks,
Currently I'm not sure about the reason for a error entry inside syslog.
Maybe you can point me to right direction.
During last night I received this log entries:

During this time it could be that autovacuum was running (its manually
set to run after a data update has been successfuly done before.)
Its a 8.4.10 running on Debian Stable. Now I'm wondering whether an
issue with postgres itself or hardware or any other part of debian....
cheers,
Frank
