That's one possibility that I was wondering about; another was there
somehow being two entries in pg_shadow for the same usesysid, which'd
result in apparent "duplicate" output from queries that involve joining
pg_database and pg_shadow. That's why I wanted to know exactly what
was leading to the conclusion that there were duplicate databases.
