The strange thing is when I try:

    select start_date from show_date order by case when start_date > CURRENT_DATE then 'start_date asc' else
'start_datedesc ' end; 

It lists start_date's without ordering them (does nothing).

However if I try:

    select start_date from show_date order by 'start_date desc';

I get a:

    ERROR:  non-integer constant in ORDER BY

Bug? Inconsistency?
