+       Previously such cases would result in converting the <type>int8</>
+       values to <type>float8</> and then using
+       the <type>money</>-and-<type>float8</> operators.  The new behavior
+       avoids possible precision loss.  But note that division
+       of <type>money</> by <type>int8</> now truncates the quotient, like
+       other integer-division cases, while the previous behavior would have
+       rounded.
