Your code is probably crashing.  Before trying to use the index, run
"select pg_backend_pid()" in the backend that you're going to try to
use it from.  Then use "gdb -p <pid>" to attach gdb to the backend.
Type "c" for continue.  Now run the query that crashes it.  gdb will
trap the signal and you can use "bt" to get a backtrace.

I don't think it would be appropriate for us to help you debug your
class project, but learning to use gdb should help you a lot.
