Cause ALTER INDEX OWNER to generate a warning and do nothing, rather than
erroring out as it has done for the last couple weeks. Document that thisform is now ignored because indexes can't usefully have different ownersfrom their parent tables. Fix pg_dump to not generate ALTER OWNER commandsfor indexes.
