It seems does not mention that if target table is a foreign/temp table, a parallel table scan may be used.
So how about:
+ <para>
+ Where the target table is a foreign/temporary table or the above target table features
+ are determined to be, at worst, parallel-restricted, rather than parallel-unsafe,
+ at least a parallel table scan may be used in the query plan for the
+ <literal>INSERT</literal> statement. For more information about Parallel Safety,

+ </para>
