Alexander Lakhin noted an obsolete comment, which led me to revisit some other important comments in the patch, and that study turned up a couple of unintended ways in which the chunked-fetch code path didn't match the normal code path in ExecQueryAndProcessResults. The only nontrivial problem is that it didn't call PrintQueryStatus, so that we'd not print the final status result from DML ... RETURNING commands. To avoid code duplication, move the filter for whether a result is from RETURNING from PrintQueryResult to PrintQueryStatus.
