This thread is about consistency of the global variables with what's set
by the GUC infrastructure.

In v4, Peter posted a 2-patch series with my patch as 001.
But I pointed out that it's better to fix the initialization of the
compile-time GUCs rather than exclude them from the check.
Then Peter submitted v5 whcih does that, and isn't built on top of my
patch.

That's a separate thread regarding consistency of the default values
(annotations) shown in postgresql.conf.  (I'm not sure whether or not my
patch adding GUC flags is an agreed way forward, although they might
turn out to be useful for other purposes).
