Check for serializability conflicts before reporting
constraint-violation failures (Thomas Munro)
</para>
<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
serialization error if the application explicitly checked for
the presence of a conflicting key (and did not find it) earlier
in the transaction.
