+ Check for serializability conflicts before reporting

+ </para>
+
+ <para>
+ When using serializable transaction isolation, it is desirable

+ a retry might succeed. Unfortunately, this does not reliably
+ happen for duplicate-key failures caused by concurrent insertions.
+ This change ensures that such an error will be reported as a

+ the presence of a conflicting key (and did not find it) earlier
+ in the transaction.

- Check for serializability conflicts before reporting

- <para>
- When using serializable transaction isolation, it is desirable
- that any error due to concurrent transactions should manifest
- as a serialization failure, thereby cueing the application that
- a retry might succeed. Unfortunately, this does not reliably
- happen for duplicate-key failures caused by concurrent insertions.
- This change ensures that such an error will be reported as a

- the presence of a conflicting key (and did not find it) earlier
