Good idea. Attached a patch to remove the superuser check on
pg_log_backend_memory_contexts(), except in the case when trying to log
memory contexts of a superuser backend.

Using pg_signal_backend does not seem to be universally acceptable, so
I'll just drop the idea of granting to that predefined role.
