I can't remember vacuum ever removing an orphaned large object, just
cleaning up any deleted space within the objects.

There is currently no way for the system to remove orphaned large objects
- it's up to the dba or the client application.

There was a discussion about handling orphaned large objects as this is a
problem for both the JDBC & ODBC drivers.

One of the things on my list for JDBC 6.4 is solving (or a solution to)
orphaned large objects.
