ISBN: dump from 64bits and restore on 32 bits fail, Datum?

Hi,

I'm in a project where there is one development server with 32bits
architecture and all the others are 64 bits.

The server where I generate the base models (in sense of version) is a 64
bit. Dump and restore from this machine to all others 64bits development
servers works well. When I try to restore it in the 32 bits server, it
returns the following errors:

[pg9(at)server ~]$ createdb isbn -T template0
[pg9(at)server ~]$ pg_restore -d isbn /tmp/isbn.backup
*ERROR: internal size 8 is invalid for passed-by-value type*
STATEMENT: CREATE TYPE ean13 (
INTERNALLENGTH = 8,
INPUT = ean13_in,
OUTPUT = public.ean13_out,
ALIGNMENT = double,
STORAGE = plain,
PASSEDBYVALUE
);
pg_restore: [archiver (db)] Error while PROCESSING TOC:

);

pg9
...

And many errors after these ones.

I guess it's a bug in isbn code since when not using isbn/issn contrib
modules the errors doesn't shows up.

Naive I was trying to force Datum size to 8 and recompile postgresql for the
32 bits server. It doesn't work this way. :)

Now I request some help from some PostgreSQL Olympian Gods... :)
