You probably should just drop the existing database and use --create by itself.You can even use the dropdb command to avoid SQL in your script.
This seems like it is the main problem:
# dropdb postgres
# pg_restore --create <a dump with the postgres database>
>No problems
# pg_restore --clean --create <a dump with the postgres database>
>public schema already exists
So both --clean and --create are attempting to create the database.
So in the example you can either use:
# pg_restore --clean -d postgres
or
# pg_restore --create -d template1
But with the later you have to "dropdb" first - if the target database already exists
With the former you have to "createdb" first - if the target database doesn't already exist.
I agree the that exit code situation should be enhanced as well.
