Hmm, you need the source code you make your user-defined type, and to
have it work you need to compile with exactly the same options. The
easiest way to do that is to compile both the server and your lib
yourself.

That said, it can be done, you just use GDB to attach to the backend
and break on your functions. But GBD will probably irritate you unless
you compile the server for debugging also.

Have a nice day,
