Backing up PostgreSQL?

[Kirk Strauser]

I just finished reading `Unix Backup and Recovery' and realized that there
are quite a few holes in my disaster recovery plan.  In particular, I'm
looking for a way to backup PostgreSQL without taking the database offline.
I'm assuming that whatever method I use will involve writing a wrapper
script to prepare the backup, launch Amanda, then clean up afterward, but
that's about as much as I've guessed right now.
