Back-patch fcff8a575198478023ada8a48e13b50f70054766 as a bug fix.
When there is both a serialization failure and a unique violation,
throw the former rather than the latter. When initially pushed,
this was viewed as a feature to assist application framework
developers, so that they could more accurately determine when to
retry a failed transaction, but a test case presented by Ian
Jackson has shown that this patch can prevent serialization
anomalies in some cases where a unique violation is caught within a
subtransaction, the work of that subtransaction is discarded, and
no error is thrown. That makes this a bug fix, so it is being
back-patched to all supported branches where it is not already
present (i.e., 9.2 to 9.5).
