Uh, I tested pg_migrator and found a problem with this approach:
test=> select loid from pg_largeobject;
loid
-------
16385
16385
16386
(3 rows)
test=> grant all ON LARGE OBJECT 16385 to public;
ERROR: large object 16385 does not exist
I am wondering if the missing pg_largeobject_metadata row is causing
this, and again I have no way of creating one with the specified oid.
