If there is a way around that, I'd like to know it, even though it's not an issue now. pg_dump works OK, but of course you don't get the roles dumped. Fortunately, I kept script files that have all the database setup, so I just ran them to create all the relationships, & then used the pg_dump output. Worked flawlessly.

I guess I don't understand what that option does:
=>pg_dumpall -U Admin --exclude-database MailPen >zzz.sql
pg_dump: error: could not write to output file: No space left on device
pg_dumpall: error: pg_dump failed on database "MailPen", exiting
I expected a tiny file, not 3.5GB. "MailPen" is the only database
(other than what's pre-installed). Do I need quotes on the command line?
