The thing that bugs me about this if for 30,000 rows, I do 30,000 updates
after the restore. It seems *really* inefficient, not to mention slow.

I'll also have to modify pg_restore to talk to the database directly (for
lo import). As a result I will probably send the entire script directly
from withing pg_restore. Do you know if comment parsing ('--') is done in
the backend, or psql?
