Bug reference: 7967
Logged by: Pawel Kobylak
Email address: no...@noose.pl
PostgreSQL version: 9.1.3
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
Expected - or at least documented.
You are looking for "isoyear" instead of "year":
select extract(isoyear from date '2012-12-31')
Result: 2013
The same "option" is available for the to_char() function: IYYY vs. YYYY
