Re: BUG #13681: Serialization failures caused by new multixact code of 9.3 (back-patch request)

I'm looking at this open bug again.  I attach two commits; the first one
adds two test cases illustrating the current (broken) behavior, and the
second one adds the fix and changes the test cases to match the new
behavior.  I spent a lot of time trying to find (a) any other
HeapTupleSatisfiesUpdate caller that needed to be changed, and (b)
additional test cases that showed misbehavior, and so far I haven't been
able to come up with any.

No other test case is affected AFAICS.

I intend to push this and backpatch to 9.3.
