If so, see https://www.postgresql.org/docs/current/static/kernel-resources.html#SYSTEMD-REMOVEIPC If it's not systemd, I'd still say that something kneecapped your PG server by removing its semaphores. Restarting the postmaster will clear the problem transiently, but do nothing to prevent a recurrence. regards, tom lane
