+ Fix concurrent locking of tuple update chains (Álvaro Herrera)
+ </para>
+
+ <para>
+ If several sessions concurrently lock a tuple update chain with
+ nonconflicting lock modes using an old snapshot, and they all
+ succeed, it was possible for some of them to nonetheless fail (and
+ conclude there is no live tuple version) due to a race condition.
+ This had consequences such as foreign-key checks failing to see a
+ tuple that definitely exists but is being updated concurrently.
