Sounds good to me. We've had the original behaviour since 7.1, I can 
understand there may be a desire to make it consistent with the 
carr-on-regardless behaviour of psql, but changing it in one release 
without the ability to revert to old behaviour is not ideal.

I expect a script (shell, perl, or sql) to die when it hits an error; 
carr-on-regardless is IMO dangerous and just a hangover from piping to 
psql. One possible problem is illustrated by:
 - dump a db - use pg_restore in 'create' mode - for some reason DB creation fails

result: template1 (or other DB) ends up with junk. Or ends up with deleted 
tables if the initial connection was to a db with the same table names.

One of my motivations in doing the original pg_dump restructure and custom 
dump format was to allow for better error handling during a restore.
