>From 5ee22be88b9d3501266807811ef37136794ff1df Mon Sep 17 00:00:00 2001
From: Justin Pryzby <pryz...@telsasoft.com>
Date: Thu, 26 Mar 2020 22:08:40 -0500
Subject: [PATCH v13 3/4] Parenthesized syntax: VACUUM (FULL, TABLESPACE ..)..
..it seems to be impossible to use "VACUUM FULL t TABLESPACE ts" since
"tablespace" isn't a fully reserved word?
Parenthesized list is the intended way to add new options anyway.
CLUSTER doesn't take parenthesized list (but maybe it should), otherwise we'd
do this there, too.
