I have looked into that in some more detail, and here is what you can do:

- Edit "src/backend/port/sysv_shmem.c" and remove the three lines

  #ifndef EXEC_BACKEND
  #define USE_ANONYMOUS_SHMEM
  #endif

  Then PostgreSQL will be built using System V shared memory.

- Wait for PostgreSQL v12.

  Commit f1bebef60ec8f557324cd3bfc1671da1318de968 has introduced a
  configuration parameter "shared_memory_type" that you can set to
  "sysv" to use System V shared memory.

PostgreSQL v12 is due this fall.
