I looked over the patch and it seems to continue on pg_restore errors by
default.  That isn't good.  By default, any error should make it exit
loudly.

I can see value in having a flag that allows pg_restore to continue on
errors, particularly because only pg_restore can read binary dumps.  Do
folks get pg_restor failures frequently?  I sure hope not.
