Please note that 0002 does not apply anymore, there are conflicts in
heap.c and tablecmds.c, and that there are noise diffs, likely because
you ran pgindent and included places unrelated to this patch. Anyway,
I am not really a fan of this patch. I could see a benefit in
switching to an enum so as for places where we use a switch/case
without a default we would be warned if a new relkind gets added or if
a value is not covered, but then we should not really need
RELKIND_NULL, no?
