Add pairingheap_initialize() for shared memory usage The existing pairingheap_allocate() uses palloc(), which allocates from process-local memory. For shared memory use cases, the pairingheap structure must be allocated via ShmemAlloc() or embedded in a shared memory struct. Add pairingheap_initialize() to initialize an already- allocated pairingheap structure in-place, enabling shared memory usage.
