That seems a bit odd. Are the two pid columns exactly the same datatype
(and what is it anyway)? What plan does EXPLAIN show for that SELECT,
and what plan do you see for
SELECT fk.pid FROM ONLY asientry fk
LEFT OUTER JOIN ONLY pobject pk
ON pk.pid=fk.pid
WHERE pk.pid IS NULL AND fk.pid IS NOT NULL;
(which is what is probably being used to test foreign key validity)?
