Ops, sorry, you're right - postinit.c:InitCommunication():
   if (!IsUnderPostmaster)     /* postmaster already did this */   {       PostgresIpcKey = key;
AttachSharedMemoryAndSemaphores(key);  }
 

Though, AttachSharedMemoryAndSemaphores():
   if (key == PrivateIPCKey)   {         CreateSharedMemoryAndSemaphores(key, 16);       return;   }

... and useless shmem attachment stuff follows after this ...

Cleanup is still required, but subj is closed, thanks -:)
