gettext, plural form and translation

Hi, all.

gnu gettext have support for correct plural form translation
(http://www.gnu.org/software/gettext/manual/html_node/Plural-forms.html),
but postgresql does not use it. why not ?
maybe it have some problem in some supported OS ? if not, can it implemented ?
maybe someone already doing this ?

ps: i try to translate psql message "(1 row)/(3 rows)" but can't do this
correctly without plural form support.

need some work with source for implement it and xgettext params used for
extract messages for http://babel.postgresql.org/

Thanks for comments !
