Don't indisready and indislive need to be checked?

The patch seems to change pg_dump so that it ignores an invalid index only
when the remote server version >= 9.0. But why not when the remote server
version < 9.0?

I think that you should start new thread to get much attention about this patch
if there is no enough feedback.

Yeah... Will send a message about that...

What's the conclusion of this discussion? pg_dump --binary-upgrade also should
ignore an invalid index? pg_upgrade needs to be changed together?

The conclusion is that pg_dump should not need to include invalid indexes if it is
to create them as valid index during restore. However I haven't seen any patch...
