Well, basically, you can't have that. Example: you have an existing
table with primary key, and while you're in the middle of doing some
long transaction, somebody else creates a table with a foreign-key
reference to the one you're about to do a delete from. Being
serializable does not excuse you from the obligation to check for
FK violations in that "invisible" table. It might be acceptable to
fail entirely, but not to act as though the table isn't there.
