Re: BUG #4274: uuid returns duplicate values - Mailing list pgsql-bugs

Hi.

uuid of MS is the approach different from ossp. Then, I regret that it can't
provide on other platforms....But, I tried it.
http://winpg.jp/~saito/pg_work/OSSP_win32/try-uuidwin32/
If someone wishes, I think that this is the place where pgfoundry is suitable.

Therefore, I will work an effort to clear the bug of uuid-ossp persistently.
Please give me time to a slight degree.

I appreciate your perseverance. thanks!

Regards,
Hiroshi Saito
