Thread: pgsql: Prevent memory context logging from sending log message to conne
Prevent memory context logging from sending log message to connected client. When pg_log_backend_memory_contexts() is executed, the target backend should use LOG_SERVER_ONLY to log its memory contexts, to prevent them from being sent to its connected client regardless of client_min_messages. But previously the backend unexpectedly used LOG to log the message "logging memory contexts of PID %d" and it could be sent to the client. This is a bug in memory context logging. To fix the bug, this commit changes that message so that it's logged with LOG_SERVER_ONLY. Back-patch to v14 where pg_log_backend_memory_contexts() was added.
