Q: 

How to delete all databases on Postgres?

I take daily backs of our postgres development box using: pg_dumpall -h 127.0.0.1 -U user -w | gzip blah.gz

Since 9.0 is now a release candidate I would like to restore this daily backup on a daily basis to a postgres9.0rc1 box for testing, however I'm not sure how to script it repeatedly. Is there some directory I can nuke to do this?

+1  A: 

You can do "drop cluster" and "create cluster" which will automtically erase all databases. Erase all data in you $PGDATA directory and reinit the cluster using:

initdb -D /usr/local/pgsql/data
