Sorry, that query reflects some munging I did to it. The real part added
to the query is:
EXISTS (SELECT 1 FROM pg_attribute at LEFT JOIN pg_init_privs pip ON(c.oid
= pip.objoid AND pip.classoid = (SELECT oid FROM pg_class WHERE relname =
'pg_class') AND pip.objsubid = at.attnum)WHERE at.attrelid = c.oid AND
((SELECT array_agg(acl) FROM (SELECT
unnest(coalesce(at.attacl,acldefault('c',c.relowner))) AS acl EXCEPT SELECT
unnest(coalesce(pip.initprivs,acldefault('c',c.relowner)))) as foo) IS NOT
NULL OR (SELECT array_agg(acl) FROM (SELECT
unnest(coalesce(pip.initprivs,acldefault('c',c.relowner))) AS acl EXCEPT
SELECT unnest(coalesce(at.attacl,acldefault('c',c.relowner)))) as foo) IS
NOT NULL OR NULL IS NOT NULL OR NULL IS NOT NULL))AS changed_ac
