Konstantin Knizhnik made off-list review of this patch and spotted few problems. * Incorrect reasoning that ON COMMIT DELETE truncate mechanism should be changed in order to allow preparing transactions with read-only access to temp relations. It actually can be be leaved as is. Things done in previous patch for ON COMMIT DELETE may be a performance win, but not directly related to this topic so I've deleted that part. * Copy-paste error with check conditions in relation_open/relation_try_open. Fixed version attached. -- Stas Kelvich Postgres Professional: http://www.postgrespro.com The Russian Postgres Company
