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.
