Postgres 8.3 server. I believe the culprit is from the sort in the query,
but its running out on queries that return 300,000 results which I didn't
think was very large.
work_mem is set to 128MB, but I thought the server would change to an
on-disk sort method if it couldn't perform the sort in memory. Is this not
the case?
In the log file, I see the following information:
2008-08-16 02:02:43 CDT lms_nna ERROR: out of memory
2008-08-16 02:02:43 CDT lms_nna DETAIL: Failed on request of size 16384.
