The simplest way is to run pg_dump from a cron job and redirect the
output to a file.  You can name the file whatever you want.  The
output of pg_dump is SQL that will create and populate your database.

To restore, feed the dump file to 'psql'.

Note that if you're using large objects it gets a little more
complicated and you have to use 'pg_restore' rather than 'psql' for
restores.
