What? I thought what you wanted back was the void * pointer that had
been registered with a particular callback function. So you use that
callback function. If it's not actually registered, you get a NULL.

This is all wrong IMHO, not least because it creates ABI problems if you
want to add another hook type later. Register each hook separately, eg
typedef void (*PGCRHook) (PGconn *conn, void *passthrough);
void PQregisterConnResetHook(PGconn *conn, PQCRHook func, void *passthrough);
... repeat for each possible hook ...
