Sure, but the tuple itself could contain something with double alignment. If you have a bigint or double in the tuple then heap_form_tuple needs to know where to put it so it ends up at right alignment. -- Gregory Stark EnterpriseDB http://www.enterprisedb.com Ask me about EnterpriseDB's Slony Replication support! -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
