I intend to look at both problems simultaneously, i.e. decoupling the current attnum in three columns as previously discussed; as Tom says, I think it'll end up being less work than attacking them separately. However, I will not attempt to include optimizations such as avoiding padding, in the first patch, just the possibility that it is added later. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
