OK, thanks.

Core was generated by `postgres: postgres acti [local] COPY '.

Here, you need to type:

   bt

and press enter. That requests the backtrace that shows the function calls leading up to the crash. Without that all we know is that it crashed in strlen(), which isn't very useful since it was probably a null pointer dereference caused by an argument passed to it from elsewhere.
