You shouldn't go mucking about with the system tables unless absolutely
necessary. Instead, write a SELECT that outputs the appropriate syntax.
You could do that by querying the catalogs directly, but I think you'll
find the pg_user_foreign_keys view defined by
http://pgfoundry.org/projects/newsysviews to be most helpful.
