This would mean we would have to go over the data inserted by the subtransaction and mark it as "subxact frozen". Some sort of sub-vacuum if you will (because it obviously needs to work inside a transaction). Doesn't sound real workable to me. -- Alvaro Herrera http://www.CommandPrompt.com/ The PostgreSQL Company - Command Prompt, Inc. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
