Modified files:
	src/backend/commands: tablecmds.c 

Log message:
	Adjust setRelhassubclassInRelation() to not perform actual heap_update
	when the pg_class.relhassubclass value is already correct.  This should
	avoid most cases of the 'tuple concurrently updated' problem that
	Robert Creager recently complained about.  Also remove a bunch of dead
	code in StoreCatalogInheritance() --- it was still computing the complete
	list of direct and indirect inheritance ancestors, though that list has
	not been needed since we got rid of the pg_ipl catalog.
