pg_restore --single-transaction has the setup to make use of the new
COPY FREEZE optimization.
However, I don't see us using COPY FREEZE for pg_restore
--single-transaction. Shouldn't we do that? The problem is we would
need to have pg_dump emit the FREEZE, which would cause it not to load
in earlier versions of Postgres, and to (soon) emit a NOTICE for
non-single-transaction loads in all other cases. :-(
Can pg_restore inject FREEZE itself when it does the copy?
