Boa tarde

Estou tentando rodar um arquivo no cron do meu linux e retorna este erro

lijnux:/usr/local/mig# su -l postgres -c 'psql mig </usr/local/mig/script_bkp_mig_crontab.txt'
You are now connected to database "mig".
ERROR: operator too long at or near "******************************************
*************************" at character 1
LINE 1: ************************************************************...

Alguem saberia me dizer o porque deste errro
