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.

Fix concurrent locking of tuple update chains (Álvaro Herrera)

<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.

Fix concurrent locking of tuple update chains (Álvaro Herrera)

<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.
