Speaking only theoretically for now but one "use case" I can vaguely imagine
would be something we are working on right now:

We have a large SQL Server database with many individual records and we are
now building a PostgresQL 8.1 database on another machine to contain
statistics about these records (e.g. for each hour in the life of the
database, how many records of each type were created or updated).  One is
derived from the other and contains aggregates of records but maybe when
we'll get the web interface to dig the stats database we might want to be
able to say "list all records in the main db which were counted by a
particular record in the stats DB".

HTH,
