That's been the traditional spelling of those variable names since
before I got here.  Do we need to change it?

Not a whole lot we can do about that, unless you want to invent a new
category of "integer variables we display in octal".  Doesn't really
seem worth it.

Neither.  It defaults to an empty string, which is interpreted as
"unset" by SHOW, but the code in postmaster.c takes that to mean "use
the machine name".  This is documented someplace but maybe not enough
places...
