Copying the pg_class table, with oids and indexes, with and without the addition of one timestamp column, the timestamp column caused the copy to be about 11.3% larger; so I see your point. I guess I didn't realize just how tight the pg_class table was. Given all that, I'm going to say that from my perspective I don't think the convenience of saving the information is worth the cost, with either approach. I understand it might mean more to others. -Kevin
