There is no way to put it on the command line, and you wouldn't want to
use it if there was, because that would expose the password to anyone
able to run "ps".  Instead, put the password in a ~/.pgpass file for the
user running the perl script.  See
http://www.postgresql.org/docs/8.2/static/libpq-pgpass.html
