I agree that if partition pruning has bugs, somebody might want to turn it off. On the other hand, when they do, there's a good chance that they will lose so much performance that they'll still be pretty sad. Somebody certainly could have a workload where the pruning helps, but by a small enough amount that shutting it off is acceptable. But I suspect that's a somewhat narrow target. I'm not going to go to war over this, though. I'm just telling you what I think. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
