I tried to go through the discussion that happened upthread, following is what I could grasp: 1) Documenting internal functions that are being used by some of the views in system_views.sql: These functions have entries in the pg_proc catalog and users are not restricted from using them. I agree that the same permissions should be applied for the views and those functions. If at all, others agree to document them, it should be discussed separately and not in this thread as there are lots of functions. Personally, I'm against documenting them all. 2) Removal of superuser() checks in all (if possible) or some of the functions as suggested in [1]: actually the list of functions having superuser() checks is huge and I'm not sure all agree on this. It should be discussed separately and not in this thread. I would like to confine this thread to allowing non-superusers with a predefined role (earlier suggestion was to use pg_read_all_stats) to access views pg_backend_memory_contexts and pg_shmem_allocations and functions pg_get_backend_memory_contexts and pg_get_shmem_allocations. Attaching the previous v2 patch here for further review and thoughts.
