Thanks for the report, investigation and patch. I've pushed and backpatched this to 15. v14 doesn't have the RelOptInfo.live_parts field, so it didn't suffer from the issue. Technically, 15 isn't broken either as the bms_del_member() function in that version wouldn't pfree the set. I decided to patch 15 anyway to keep the code the same and to avoid assuming it's ok to ignore the return value of bms_del_member(). > This is admittedly a pretty remote edge case, but still, better safe > than sorry. Did you find it through code analysis or from a crash? It would just have been a matter of time before someone hit this. David
