The current patch doesn't allow members of pg_signal_backend to rotate the log file. Do you think pg_signal_backend is the wrong group to allow usage of pg_log_backend_memory_contexts()? Alternatively, it could simply not GRANT anything, and leave that up to the administrator to choose who can use it. Regards, Jeff Davis
