year and weeknumbers (proposal included) - Mailing list pgsql-bugs

hi,

last year (2002) the date december 31st is in week 1 of 2003.

it is not possible to get this out of a date-column using EXTRACT or
to_char.
         to_char( '2002-12-31', 'WW' ) returns 1, and
         to_char( '2002-12-31', 'YYYY' ) returns 2002 (as expected)!

the format for retrieving the year with respect to week-numbering
could be something like IY, IYY, IYYY, IYYYY.

         to_char( '2002-12-31', 'IYYYY' ) returns 2003.

regards,

Joost Helberg
