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.
