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.

cc -shared, I believe...

Add CFLAGS+= -Wall -Werror (should only affect developers, not users)

Add #include "postgres.h" as required

Remove #include "c.h" *and* "utils/elog.h" as applicable

Add #include "postgres.h" as required

Remove #include "utils/elog.h"

Compiled with -Wall -Werror

include files properly...yet, slowly...

access/tupdesc.h
	catalog/pg_attribute.h
	nodes/pg_list.h
		nodes/nodes.h
	access/attnum.h

	Based on include files require by htup.h, as:

	access/htup.h
		storage/itemptr.h
			storage/block.h
			storage/off.h
		utils/nabstime.h
			<time.h>
