We should look for foreign key relationships that cross set boundaries from
various perspectives:

1. Foreign key on replicated table pointing to a non-replicated table
2. Foreign key on non-replicated table pointing to a replicated table
3. Foreign key on replicated table pointing to a table in a different
replication set with the same origin
4. Foreign key on replicated table pointing to a table in a different
replication set with a different origin

Other scenarios are uninteresting from a Slony perspective.

There are several ways that these issues might be reported, and we may wish to
consider using some or multiple of the following:

a) Initial health check run by slon upon startup, calling stored function
slon_node_health_check() 

b) The tool test_slony_state.pl

c) Perhaps a stand-alone tool to add to tools
