BTW, there's another pretty unpleasant thing going on here, which is
that the t1_pkey constraint is getting hoisted up to before t1's table
data because it is a dependency of v1. That means the index will be
created before the data is loaded, which is not what we want.

Parallel pg_restore actually has a hack that should work around that,
namely repoint_table_dependencies(). That doesn't help for plain serial
restores though. I'm thinking we really ought to bite the bullet and do
something comparable to repoint_table_dependencies() at an appropriate
point in pg_dump, so that the dependencies are sane to begin with.
