Yes, later we can use shared memory buffer as "pipe" betweenbackends:
Backend A: Backend B:local-memory-query-plan --> shmem --> local-memory-query-planIn this
ideais in the shared memory one query-plan only and backends use it for plan copying from "A" to "B".
It require persistent backends of course.
