pg_attribute bloat? I'm a bit hesitant to add a row per table for something we've gotten along without for so long, especially something with as bizarre a definition as "t_self" has got. At one time I was hoping to get rid of explicit entries in pg_attribute for system columns, which would negate this concern. I think we're stuck with them now, though, because of per-column permissions. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
