But there is finally some interesting message hidden in your image: server process (PID 14257) was terminated by signal 9: Killed Since I don't expect that random users on your server machine go around "kill -9"-ing PostgreSQL processes, it is very likely that PostgreSQL is crashed by the Linux out-of-memory killer. You should disable memory overcommit, see https://www.postgresql.org/docs/current/kernel-resources.html#LINUX-MEMORY-OVERCOMMIT Then you will start getting "out of memory" errors instead of crashes. To combat these, reduce the memory usage parameters, mostly "work_mem", or reduce the number of active database sessions by using a connection pool. Yours, Laurenz Albe
