Your work_mem is perfectly reasonable. The plan looks pretty harsh, with that big nested loop, but I'm not aware of anything that'd cause that to run out of memory. Personally I'd be attaching a debugger to it and seeing what it was doing while it ran. I'm sure there are smarter ways to trace where the memory use is going, though. -- Craig Ringer -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
