If failures happen with CREATE INDEX CONCURRENTLY, the system will be let
with invalid indexes. I don't think that the user would like to see invalid indexes of
an existing system being recreated as valid after a restore.
So why not removing from a dump invalid indexes with something like the patch
attached?
This should perhaps be applied in pg_dump for versions down to 8.2 where CREATE
INDEX CONCURRENTLY has been implemented?
I noticed some recent discussions about that:
http://www.postgresql.org/message-id/20121207141236.GB4699@alvh.no-ip.org
In this case the problem has been fixed in pg_upgrade directly.
