Attached patch fixes the issue for me. I have locally verified that the gather merge gets executed in rescan path. I haven't added a test case for the same as having gather or gather merge on the inner side of join can be time-consuming. However, if you or others feel that it is important to have a test to cover this code path, then I can try to produce one. -- With Regards, Amit Kapila. EnterpriseDB: http://www.enterprisedb.com
