Hello,

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/018d01c8dec6$2a14b470$0b01a8c0@IBMC9A0F63B40D
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:

http://www.postgresql.org/message-id/SNT127-W18C42125E5FD719BA514CEFF1F0@phx.gbl

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?

MauMau
