    Fix AfterTriggerSaveEvent to use a test and elog, not just Assert, to check · 44956c52
    Tom Lane authored
    that it's called within an AfterTriggerBeginQuery/AfterTriggerEndQuery pair.
    The RI cascade triggers suppress that overhead on the assumption that they
    are always run non-deferred, so it's possible to violate the condition if
    someone mistakenly changes pg_trigger to mark such a trigger deferred.
    We don't really care about supporting that, but throwing an error instead
    of crashing seems desirable.  Per report from Marcelo Costa.
