Yes. 'week' is "ISO week" (new for 7.0 afaicr). And it wasn't *entirely*
trivial to implement, so you may want to steal code for to_char() ;)
I just didn't implement the corresponding "year" code at least partly
because I wasn't sure what to call it. 'iyear' seems like a pretty good
choice, or should it be 'isoyear'? 'year' is already used, obviously,
and if 'iyear' is chosen then perhaps I should change 'week' to 'iweek'
for consistancy. Comments?
