LINE COMMAND - Mailing list pgsql-bugs

I would like to run a line command (psql) with the supplied password without
pausing the command, but this option is not available:

psql --username=3Droot --password=3Droot my_bd < "script.sql"

The pass only can be informed after execution, pausing the command:

psql --username=3Droot --password my_bd<script.sql
Senha para usu=DFrio root: ****

Thanks.
