In 8.4, yes. In later versions, you'd need to do something about
creating corresponding rows in pg_largeobject_metadata.
In general, all built-in OID columns have mechanisms for choosing
nonconflicting new values --- but in 9.0 and up, pg_largeobject_metadata
is the authoritative store of "existing OIDs" for blobs, not
pg_largeobject.
