pgjdbc has a bug report which is as follows:

The database has a table that has a description and a constraint.
The constraint also has a description.

somehow the constraint and the table end up with the same OID's after
pg_upgrade.

My understanding of pg_upgrade suggests that shouldn't happen ? I realize
oids are not guaranteed to be unique, but this seems to be quite a
coincidence.
