Bug reference: 15268
Logged by: D. Ebdrup

PostgreSQL version: 10.0
Operating system: FreeBSD
Description:
Owing to some rather big changes in FreeBSD, the steps recommended in the
documentation for all supported (and unsupported) versions of pgsql on
FreeBSD 11 and future versions regarding sysvipc are no longer accurate.
Notably, the security.jail.sysvipc_allowed sysctl has been marked deprecated
(ie. to be removed in a future version) and the sysvmsg, sysvsem, and
sysvshm properties for jails have been added which can function like
security.jail.sysvipc_allowed/allow.sysvipc used to work, in addition to
which a value named "new" has been added which offers proper per-jail
isolation of SysV messages, semaphores and shadow memory.
This can be confirmed by going to https://man.freebsd.org/jail(8) and
searching for the second result of sysvmsg as a text-search.
