Query on support for trigger functions defined in a Shared librar y in Windows

Hi,

I would like to know whether the native Windows version of PostgreSQL
(version 8.0.0)
supports trigger functions defined in shared libraries. Specifically, I am
trying to port a
Linux shared object used as the snippet below shows to Windows:

CREATE FUNCTION foo() returns trigger AS '/path/to/sharedlib.so' LANGUAGE C;

Are DLLs supported in a similar context in Windows?

What do I need to do to port such code?

My initial attempts resulted in a failure. I created the DLL and attempted
to run the SQL CREATE FUNCTION which specified the Windows path
to the DLL. However the server died without any clueful messages.

psql:d:/test.sql:4: server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
psql:d:/test.sql:4: connection to server was lost

The pg_log logs the following:
