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. regards, tom lane
