Nope. Postgres data directories are not usually compatible across different architectures. If you'd gone 32->64 you could install a 32-bit build of Postgres and do something with that, but in this direction I'm afraid you're out of luck. Borrow an amd64 machine from somebody for long enough to run pg_dump ... regards, tom lane
