The variable is called `source` but the comment says `target`. Also maybe the procedure should take those parameters in a different order? For example, I think `CALL %s.system.fast_forward(table => '%s', branch => '%s', source => '%s')"` is less clear than `CALL %s.system.fast_forward(table => '%s', source => '%s', target => '%s')"`.
