Bug reference:      7967
Logged by:          Pawel Kobylak

Operating system:   Debian
Description:        =


Hi,
I'm running that query and result is ... unexpected for me...

Query:
select '2012-12-31', EXTRACT(year from '2012-12-31'::date), EXTRACT(week
from '2012-12-31'::date)

Result:
"2012-12-31";2012;1

Expected:
"2012-12-31";2012;53
OR
"2012-12-31";2013;1

This result is correct? Or that is little bug? :-)
Regards,
Pawel
