Yeah. The claimed problem is unreachable, because the only way to get
there is for configOutLefttype/configOutRighttype to have been set to
something valid by a previous execution of the SPGIST_CONFIG_PROC case.
However, if the proclist members don't appear in numerical sequence,
we'd get a bogus failure because the "ok = false" path would be taken.
That "if" is true normally because of the way the catcache works, but
I think it's possible to make it fail if you disable system index usage.
Not a realistic scenario in practice, but less robust than I'd like.
Can't get terribly excited about fixing it though.
