Not doing to well here. When will the ISO year be greater than the current
year? But, what I did is incorrect and 2006-01-01 shows the next problem date:
SELECT '' AS date_trunc_week, date_trunc( 'week', timestamp '2006-01-01' ) AS
week_trunc;
date_trunc_week | week_trunc
-----------------+--------------------- | 2006-12-25 00:00:00
Heck, even what I submitted, test and all is wrong:
SELECT '' AS date_trunc_week, date_trunc( 'week', timestamp '2005-01-01' ) AS
week_trunc;date_trunc_week | week_trunc
-----------------+--------------------- | 2005-01-02 00:00:00
The date should be 2005-01-03. Sigh. Maybe I should of just submitted a bug
report about it...
So, unless someone else knows how to do this correctly, I'll have to actually
think about it.
Cheers,
Rob
