The documentation does not talk about a shared library for Windows
(http://www.postgresql.org/docs/8.1/interactive/xfunc-c.html#DFUNC)
I tried to compile its custom types with borland bcc32, with 
no success:

Does somebody can help me ?
   

You need to compile the functions using MingW GCC.

Thanks again for your answers.
Now, when I try to generate the shared library by the following command:
gcc -shared -o pstypes.dll -Wl,-dy,--library-path,/c/Program\ Files/PostgreSQL/8.1/lib/,-l,libpq.a,--out-implib,pstypes.a country.o

the compiler response is:
c:\MinGW\bin\..\lib\gcc\mingw32\3.4.2\..\..\..\..\mingw32\bin\ld.exe: cannot find -llibpq.a
collect2: ld returned 1 exit status

but the libpq.a is in the lib repository of PostgresSQL...

I tried to link with the libpq.dll located in the bin repository, the response is the same: cannot find -llibpq.dll

In fact, the true command is
gcc -shared -o pstypes.dll -Wl,--library-path=/c/Program\ Files/PostgreSQL/8.1/lib/,-l,pgport,-lpostgres,--out-implib,pstypes.a country.o

and the response is
