Well, that would do as a quick workaround, as would disabling autovacuum
during the restore.

Ugh.  I think a real solution probably involves a mechanism that kicks
autovacuum off a table when someone else wants an exclusive lock on it.
This is a little bit worrisome because a steady stream of lock requests
could prevent autovac from ever finishing the table, but it seems clear
that not doing this is going to make autovac a lot more intrusive than
people will stand for.
