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