Consult experts, postgreSQL local_map and shared_map two mapping table inside, have what differentia

Time：10-12

Each mapping table can only support 62 mapping, I see local_map content is much lower than shared_map

But I didn't understand what is the difference between the two mapping table, local and Shared in the request, and run on, what's the difference?

If you want to add a map, how to judge should be added to the local, or in the Shared?

If shared_map full, increase, how to do?
