I dunno, if you close a portal before you've gotten CommandComplete,
should you expect that all its actions were taken? Arguably, that
should be more like a ROLLBACK.
Note there'd only be a difference in case of an operation with RETURNING,
else there's no way (at this level anyway) to pause a data-modifying
command mid-execution. This logic all predates RETURNING, I think,
so maybe it does need to be revisited. But it's not entirely clear
what should happen.
