i read in the postgresql 6.4 announcement yesterday that it includes a new
program called pg_upgrade.

    PostgreSQL 6.4               Mon Oct 26 11:40:42 EST 1998

    A dump/restore is required for those wishing to migrate data
    from previous releases of PostgreSQL.  You may also use the new
    pg_upgrade utility to avoid a dump/reload.

have you tried this?  is it safe to use for an automated upgrade?

BTW, i have some non-critical postgresql servers if you need a guinea-pig
