Hello , https://github.com/postgres/postgres/blob/5d39becf8ba0080c98fee4b63575552f6800b012/src/backend/optimizer/prep/prepjointree.c#L3856 bms_next_member() is allowed to return the zero as a valid value. Subsequent rt_fetch() offsets that zero to -1 which leads to the assertion down the code. Nothing wrong here? Either zero is simply not possible after that bms_next_member() because of some factors behind the code?
