Previously database attributes like GRANT/REVOKE permissions and ALTER

dumped by pg_dumpall. Now pg_dump --create and pg_restore --create

A restore of pg_dumpall will now create databases with their original
locale and encoding, and will fail if the creation fails. Previously
CREATE DATABASE would be dumped without such specifications if the
database locale and encoding matched the old cluster's defaults.
