recreated since the start of our transaction, our first reference to it errored out because we'd try to reuse our old relcache entry for it. Do this by accepting SI inval messages just before relcache search in heap_openr, so that dead relcache entries will be flushed before we search. Also, break heap_open/openr into two pairs of routines, relation_open(r) and heap_open(r). The relation_open routines make no tests on relkind and so can be used to open anything that has a pg_class entry. The heap_open routines are wrappers that add a relkind test to preserve their established behavior. Use the relation_open routines in several places that had various kluge solutions for opening rels that might be either heap or index rels. Also, remove the old 'heap stats' code that's been superseded by Jan's stats collector, and clean up some inconsistencies in error reporting between the different types of ALTER TABLE.
