Unfortunately vacuumlo doesn't take type lo into account.

I changed vacuumlo so that it takes the type lo into
account in 7.2 but it doesn't handle the following
type created by
 create type lo (
   internallength=4,
   externallength=10,
   input=int4in,
   output=int4out,
   default='',
   passedbyvalue
 );

The type is incomplete and hard to handle in vacuumlo
or pg_restore. In 7.2 both vacuumlo and pg_restore
could handle the type lo defined in contrib/lo which
contains the definitions of input/output functions
etc.
Probably I had better recommend to use the type lo
in contrib/lo and change the documentation at http:
//odbc.postgresql.org/. However PostgreSQL hasn't
had a proper BLOB type yet and I don't know what
would occur about BLOB in the future.
