Why not just add a few dummy columns onto each catalog table? If we need space to expand a row we can just drop one of the dummy columns from the new catalog definition. That's an old DBA trick to avoid having to rewrite a table when you want to add a column. Seems much simpler to add columns than write special code, especially when we might find the new code has bugs and hasn't done what we thought it might. -- Simon Riggs www.2ndQuadrant.com PostgreSQL Training, Services and Support -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
