Tom Lane 3ae7e4a33b Remove BufferBlockPointers array in favor of a base + (bufnum) * BLCKSZ ... computation. On modern machines this is as fast if not faster, and we don't have to clog the CPU's L2 cache with a tens-of-KB pointer array. If we ever decide to adopt a more dynamic allocation method for shared buffers, we'll probably have to revert this patch, but in the meantime we might as well save a few bytes and nanoseconds.
