Note.  all include files that have been hit so far have had extraneous
       include files cleaned out and are reduced to...the lowest common
       "include file", based on 'cc -Wall -I. test.c', where test.c is:

#include "postgres.h"
#include "<top of branches>" (ie. top of branches this time was utils/fcache2.h)

working on it)

that it depends on

not

Bryan's superuser() function

cleaning up behind myself before *yawn* bed :)

rather than in src/include with normal header files.  Necessary to make
dependancies work out so they don't keep getting rebuilt for no reason.
