findoidjoins
This program scans the a database, and prints oid fields, and the tables
they join to. PostgreSQL version 6.3.2 crashes with aggregates on
views, so I have removed the view pg_user from the list of relations to
examine.
Run on am empty database, it returns the system join relationships:
