We disable statement_timeout and lock_timeout during dump and restore, to
prevent any global settings that might exist from breaking routine backups.
Commit c6dda1f48 should have added idle_in_transaction_session_timeout to
that list, but failed to.
Another place where these timeouts get turned off is autovacuum. While
I doubt an idle timeout could fire there, it seems better to be safe than
sorry.
