This view displays the usages of all the memory contexts of the server process attached to the current session. This information is useful to investigate the cause of backend-local memory bloat. This information can be also collected by calling MemoryContextStats(TopMemoryContext) via a debugger. But this technique cannot be uesd in some environments because no debugger is available there. And it outputs lots of text messages and it's not easy to analyze them. So, pg_backend_memory_contexts view allows us to access to backend-local memory contexts information more easily.
