Since you changed ACL_WORLD_DEFAULT to ACL_NO too, there are
now problems on \d <table> (pg_attribute: Permission denied).
And thus I expect more problems. I think users should have
SELECT permission on non-critical system catalogs by default.
But I don't think that setting explicit GRANT's on all the
system catalogs is a good thing. Due to the ACL parsing I
would expect some loss of performance.
So if the relname is given to acldefault() in
utils/adt/acl.c, it can do a IsSystemRelationName() on it and
return ACL_RD instead of ACL_WORLD_DEFAULT.
