Greetings! I've noticed in the documentation that the sql standard
requires foreign keys to reference primary key/(or maybe just unique)
columns, but that postgresql does not enforce this. Is this a feature
that is intended to persist, or a temporary deviation from the sql
standard? The current postgresql behavior seems useful in cases where
one wants to update a foreign key to a value already in the original
table.
Take care,
