Well, as I wrote in my email, it requiers some adjustments IRW your schema,
meaning you'll have to hack around to make it fit your need.
About FK, just look at pgsql trigger code around real FK and adjust to your
need by creating custom FK trigger either in plpgsql or C. IIRC, there's a
contrib module doing FK as well, look at "contrib/spi/refint.c".
