cost_rescan assumed that we don't need to rebuild the hash table when rescanning a hash join. However, that's currently only true for single-batch joins; for a multi-batch join we must charge full freight. This probably has escaped notice because we'd be unlikely to put a hash join on the inside of a nestloop anyway. Nonetheless, it's wrong. Fix in HEAD, but don't backpatch for fear of destabilizing plans in stable releases. |
