Hi Alexander! Can you double check that this same problem doesn't occur with custom aggregate functions? There is a switch involved with cursors and custom aggregate functions here: /* Only pop cursors when we're done with group aggregate running. */ if (m_chistics.agg_type != GROUP_AGGREGATE || (m_chistics.agg_type == GROUP_AGGREGATE && thd->spcont->quit_func)) thd->spcont->pop_all_cursors(thd); // To avoid memory leaks after an error That may require a different approach.
