Large Objects and Toast

PostgreSQL: 8.2

My understanding is that when one creates a large object there is no way
to link the large object to a field in a table so that cascading delete
can occur. Is this correct? My understanding is that you have to
manually delete the large object.

I also read something about the OID ID being limited in size. What is
the size limit of this OID type? I am sure that it is bigger than the
number of files that I would be uploaded into my db; but I just want to
get an idea of the range.

When putting a reference to a large object in a table, should the type
of the reference object be OID?

Thanks,
