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_date desc ' 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?
