The argument that lots of boolean columns won't scale nicely doesn't seem to lead to the conclusion that a fixed-size bitmap is better. I'd have gone with just adding more bool columns as needed. 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
