It's best to post questions to the Postgres mailing lists, since others
may have better answers than I. However, I think you can use "triggers"
to mimic foreign key constraints. Look in the "contrib" area of the
distribution for examples. There is a change foreign keys will be in
v6.5, perhaps in 6 months. There was talk of possibly having it earlier,
but I do not have access to my Postgres e-mail at work and can't
remember if that is still true...
Good luck.
