When executing a list of queries derived from rule expansion,
_SPI_execute_plan's return code should reflect the type of the querythat is marked canSetTag, not necessarily the last one in the list.This is arguably a bug fix, but I'm hesitant to back-patch it becauseit's the sort of subtle change that might break someone's code, and it'sbest not to do that kind of thing in point releases.
