PGDATA should work fine if you always start the server directly. But if you sudo or su to another user, they likely won't inherit your environment variables. And if you use some kind of start-up script, they will likely override it. How do you start and stop PostgreSQL?
Jeff, Slackware's /etc/rc.d/rc.postgresql start command. I can modify that script to change the data directory path. Thanks, Rich
