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.
