so you real question is probably:
    how can i modify the structure of system tables ?

you do not say what your ultimate purpose is, so I cannot see if the
FOREIGN KEY reference is necessary, but if you really need it, it possibly
might be done by starting postgres in single-user mode, with correct
options.

my guess is that this should only be done by someone who knows what he is
doing.
