  1. Add capability to interleave shared memory across multiple NUMA nodes 

    Introduce new GUC numa=off(default)/on/auto that might be used to
enable interleaving shared memory. Until today, imbalances in shared memory
allocations on NUMA setups, may have caused non-deterministic performance
due to differences in latencies and bandwidths across interconnects ("remote"
access). This is only supported on Linux with libnuma.
