I realize this isn't directly addressing the problem but perhaps part of the
solution would be to start advocating the use of pg_restore -1 ? That would
solve the problem for the narrow case of pg_restore.
In the long run we could think about exposing some kind of command for
pg_restore to use which would disable autovacuum from touching a table. (Or
take a session-level lock on the table -- shudder)
