psql:postgres@cipafilter = EXPLAIN (ANALYZE, BUFFERS) select titleid from titles WHERE NOT EXISTS ( SELECT 1 FROM log_raw WHERE log_raw.titleid = titles.titleid ); server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request. The connection to the server was lost. Attempting reset: Failed. Nope, that pops too. The query runs for a long time at a somewhat normal rate of ram consumption, using ~1G of RSS then suddenly spikes to about 6G, at which point the OOM killer pops it. Box has 8G of ram and 4G of swap.
