Первая предназначена для отключения/включения быстрого перемещения к корневым узлам. Вторая для отключения/включения автоматического сохранения закладок в Query Tool. После отключения авто сохранения возможно понадобиться вручную очистить каталог с сохранёнными закладками %APPDATA%\postgresql\recovery
