Administer Postfix with this web-based tool

The following MYSQL command gives me an error:
GRANT ALL PRIVILEGES ON `postfix` . * TO 'USER'@'localhost';
====================================================
for user I am entering POSTFIX, as this is the user I created in the previous
MySql command.

Here is my setup.php results
=======================
Everything seems fine... attempting to create/update database structure
Updating database:
- old version: 654; target version: 740
updating to version 655 (all databases)...
DEBUG INFORMATION:
Invalid query: Duplicate key name 'domain'

GRANT ALL PRIVILEGES ON `postfix` . * TO 'USER'@'localhost';

I removed the tick marks from the database name and my error was resolved.

GRANT ALL PRIVILEGES ON postfix. * TO 'USER'@'localhost';
========================================================

Although, I am still getting an error when running the setup.php:
