IYYY: unexpected behaviour - Mailing list pgsql-bugs

Hi,

=20

SELECT to_char( '2006-01-01'::timestamp, 'IYYY-MM-DD' ) AS strange,

       to_char( '2006-01-02'::timestamp, 'IYYY-MM-DD' ),

       to_char( '2006-01-01'::timestamp, 'YYYY-MM-DD' );

does produce unexpected result for column 'strange':

  strange   |  to_char   |  to_char
