It's surprising that nobody noticed the bug until now. It seems it has
been there since 7.3 days. I would like to make a back patch for
7.3-stable if nobody objects.

BTW, I'm interested in Korea PostgreSQL Users' Group since I myself am
a bord member of Japan PostgreSQL Users' Group. Please let me know if
both users group could make some collaboration, such as having a
seminar in Korea or in Japan.
