I tried to set RemoveIPC=no, but it made no difference. Finally I found a solution with the hint given here: http://www.postgresql.org/message-id/56a52018.1030...@gmx.net Systemd defaults to remove all IPC (including SYSV memory) when a user "fully" logs out. This seems to be happen when running the cron job. It seems to be a difference if the job is running as a “normal” user or a “system” user. So I modified my existing postgres user to be a system user usermod -u <id below 1000> mmppostgres an now my backup is running. I cannot remember finding such a hint in the PostgreSQL documentation. It would be worth mentioning it.
