It may be that other memory settings are contributing towards this
(work_mem, maintenance_work_mem, max_connections etc).
I would suggest that the OOM killer is working as intended and something
is not quite right within the config.
You may want to review the memory consumption at peak times taking into
consideration anything else running on the machine.
