No. It's kind of a neat idea perhaps, but it's not there. You could
* use parallel pg_restore to alleviate the pain, or
* use pg_restore's -l and -L switches to strip out the FKs altogether,
and then re-add them manually afterwards.
Or there's always
* hack the pg_dump source code to include NOT VALID. While a real
feature patch that made this optional would be a bit complicated,
doing it unconditionally should be a one-line change.
