Well, the problem is that you are creating here the database with createdb.
This creates all DB objects and runs all upgrade scripts.
Then when you try to restore from your file , you have problems, since
your file also tries to create the same objects.
instead of : createdb -U postgres engine
do :
> echo "create database engine;" | psql -U postgres template1
Then continue on the next steps and it will work.

optionally, in your backup command:
instead of 
pg_dump -C -E UTF8 --column-inserts --disable-dollar-quoting
use
pg_dump --data-only -E UTF8 --column-inserts --disable-dollar-quoting

then , createdb will create the db & schema and your engine.sql will include only "insert"
