pg_dumpall for Postgres Database Daily Backup

Hi,

I'm running on Postgres 8.3.8.  My system admin is ready to set up a cron job for a daily database backup.
By reading the documentation over here: http://www.postgresql.org/docs/8.3/static/backup-dump.html#BACKUP-DUMP-ALL (I
onlyfound the documentation for 8.3.10), and it looks like pg_dumpall > outfile is the best choice.  I'd like to ask
thecommunity to reconfirm. 

Thanks in advance.
Mary
