pg_restore in 7.2 could handle the type lo defined in
contrib/lo but couldn't handle the type lo you created by
CREATE TYPE lo (
internallength=4, externallength=10,
input=int4in, output=int4out,
default='', passedbyvalue
);
The type is incomplete and hard to handle in pg_restore.

pg_restore in 7.1.x couldn't restore large objects
of type lo properly though it doesn't cause any error.
One way I can think of is to create the type lo in
contrib/lo in advance of pg_restore and ignore
the 'create type lo ..' commands in pg_restore but
it seems pretty unnatural for pg_restore.
Comments ?
I've worried about the use of type lo which has
been used only(?) in ODBC. It doesn't seem wrong
because PostgreSQL hasn't provided the proper
BLOB type. However I'm not sure now how to handle
large objects in ODBC in future.
Comments ?
