That would be appropriate for this case though, yes? That column is part of
a foriegn key, unless I've totally lost track.
As I remarked before, Postgres does *not* automatically create indexes for
FKs. Many, but not all, other database products do, so comparing PostgreSQL
against those products without the index is unfair.
