And idea that just came up around here that sounds like a pretty neat
workaround, which we're gonna try, is to drop the foreign key
constraints, and just use a check constraint for the allowed values. If
the cardinality of the reference table is small, this is much faster
than using foreign keys and solves your problem. With the drawback that
if you update the reference table (if you keep it), you mustn't forget
to also update the check constraints in more than one place.
