 * This function is used to control serializing and de-serializing of the
 * database objects. Basically there are some pointers in the structure
 * that we don't bother to serialize because they are always NULL when we
 * deserialize them. This function then simply returns on encode operations
 * and stuffs NULL into the pointer passed when decoding.
