Guard against parallel-restricted functions in VALUES expressions.
Tom Lane <tgl@sss.pgh.pa.us>
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).
