Обсуждение: pgsql: Guard against parallel-restricted functions in VALUES expression

Guard against parallel-restricted functions in VALUES expressions.

Obvious brain fade in set_rel_consider_parallel().  Noticed it while
adjusting the adjacent RTE_FUNCTION case.

In 9.6, also make the code look more like what I just did in HEAD
by removing the unnecessary function_rte_parallel_ok subroutine
(it does nothing that expression_tree_walker wouldn't do).
