no, but (IMO) 8.2.4 is a required upgrade....so you should be testing that.
The server is unable to delete a file (specifically, a temporary
table created for sorting). Have you considered any running services
that may acquire a lock on the table (windows is famous for this).
This may also suggest you need to look at the work_mem setting, but
this is not the issue at hand.
is the error repeatable?
