Would it make sense to use 08003 (connection_does_not_exist) when a
broken connection for an idle process is discovered, and 08006
(connection_failure) for the "in transaction" failure?  What about a
failure just after COMMIT and before successfully sending that
result to the client?  I notice there's a SQLSTATE 08007
(transaction_resolution_unknown), but I don't know whether that
makes sense on the server side, or just on the client side.
