I think you can use MS VC, you can try to find some info from here:
http://www.postgresql.org/docs/8.0/interactive/xfunc-c.html
Read user comments at the bottom.

In documentation it is said:
"The first time a user-defined function in a particular loadable object file
is called in a session, the dynamic loader loads that object file into
memory so that the function can be called", so I think you should try to
attach to postgres.exe (I'm not sure).

Have a nice day,
