Hello,

# Sorry, Saito san' address doesn't seem to exist, so excuse for sending 
again

For a certain reason, I need to build PostgreSQL on Windows with OSSP UUID 
support to use UUID for primary keys.  I have to use Visual Studio 2010.

The original source code for OSSP UUID and its fork for Windows can be 
downloaded from:

http://www.ossp.org/pkg/lib/uuid/
http://sourceforge.jp/projects/sfnet_osspuuidwin32/

I built the latest version 1.6.2 and used uuid_generate_v4() as the default 
value for a primary key column of type uuid.  However, when I insert 200-300 
rows, an unique constraint violation error is reported.  It occurs 
repeatedly in several retries.

I found some people hit the same problem in the past, but they didn't seem 
to get the solution:

http://www.postgresql.org/message-id/98B20744191F464DB598A25AB00BC125@acer08f817a9b5

When I copy lib\uuid_ossp.dll in the PostgreSQL community package, which I 
guess Dave Page san maintains, to my installation, the error does not occur. 
So, OSSP UUID library is the cause.

Saito san published a patch for OSSP UUID on his site:

http://winpg.jp/~saito/pg_work/OSSP_win32/msvc/

And Dave san showed interest in it:

How can I build the OSSP UUID library that functions properly on Windows? Is 
OSSP UUID 1.6.2 + Saito-san's patch the exact source for the uuid-ossp.dll 
in thecommunity binary?
