pgbulkload - pgbulkload: Add new restriction: the password must be

Log Message:
-----------
Add new restriction: the password must be specified in .pgpass file when
WRITER=PARALLEL and password is required to connect from localhost to
the database to load.

The cause of this problem is that the password that you entered in
the prompt is not passed to the child processes for parallel loading.
