Well, you need to deal with that last, because you will never get very far if you can't debug your code. My experience is that gdb needs help to recognize a shared library's symbols. It works for me to LOAD the shared library (from SQL) before attaching to the backend with gdb. If you can't do that, gdb's "sharedlibrary" command might do it. regards, tom lane
