If this is a common setup, maybe we're going to need a new section under or near https://www.postgresql.org/docs/current/static/kernel-resources.html#SYSVIPC It's pretty annoying to have sweated blood to get out from under the kernel's chosen-at-random SysV IPC limits, only to run into container tmpfs limits that seem equally chosen with the aid of a dartboard. regards, tom lane
