It is a Solomon's answer :-), but well. I agree.

OK, I add it to to_char() and to date_[ trunc | dart ].


I'm just now working on 'week' support to date_trunc().

The date_part() say that monday is a first day, to_char that it is second day,
and what will say date_trunc()? --- how date is a week start, 'monday' or 
'sunday' date ?
Comments?

(I vote for 'sunday' like first day.)                Karel
