I have replaced the "unique" with "distinct" in the postresql.xql (cal-options-postgresql.xql)file. But I still got this error
Database operation "select" failed (exception NSDB, "Query was not a statement returning rows.")
        while executing

This is the actual query in the xql file
    select   distinct(calendar_id) as calendar_id,
             ' ' as checked_p
    from     calendars
    where    acs_permission__permission_p(calendar_id, :user_id, 'calendar_read$    and      acs_permission__permission_p(calendar_id, :user_id, 'calendar_show$    and      private_p = 'f'


    select  distinct(on_which_calendar) as calendar_id,
            calendar__name(on_which_calendar) as calendar_name,
            ' ' as checked_p
    from    cal_items
