~ Bash Script to Backup Remote Postgres Databases via Cron with Password Authentication

I have modified a bash-script to backup PostgreSQL databases, this is the original script. The modified version can be used to backup databases on a remote or local database server. Also this script does not need a trust relationship but uses a login and password. To get started you need to:

1. Modify the directory and database variables to suit your needs.
2. Add an entry to crontab to perform the backups nightly or whenever you wish.
3. Have fun.

The script empties ~/.pgpass and writes login info for the system databases. Then it logs in and fetches an up-to-date list of databases. For every database an entry is made in ~/.pgpass and every database is backed up. The results are logged to $logfile.
