Surely preloading is the most realistic approach, but I hope we would support
dynamic allocation of shared memory, and load dictionaries in the area and
share it with backends. We should avoid additonal calls of shmget() or mmap()
in the additional shared memory allocation, but we can shrink shared buffers
and reuse the area for general purposes. We often have serveral GB of shared
buffers nowadays, so dividing some MB of buffers will not be problem.
