possible constraint bug?

Using Postgresql 7.0.2 (Linux x86, 2.2.16)

CERATE FUNCTION foo(text)

CREATE TABLE bar(
         fud TEXT CHECK (foo(fud))
);

DROP FUNCTION foo(TEXT);
CREATE FUNCTION foo( .....);

INSERT INTO bar VALUES ('Hey'); results in the following error

ERROR init_fcache: Cache lookup failed for procedure 128384

Is this particular to postgres or is this a normal SQLxx standard behavior?
