The specific error is an unquoted 80ms in WITH
(autovacuum_vacuum_cost_delay=80ms);
Independent of that being fixable with some quoting or such, I'm a bit
doubtful about unconditionally adding the ms here. Won't that make it
unnecessarily hard to get 9.5 dumps into <9.5? I know that we don't make
any promises, but it mostly works nonetheless. And this doesn't seem
worth the breakage.
