Re: BUG #6733: All Tables Empty After pg_upgrade (PG 9.2.0 beta 2)

core stack:
root(at)db4 / $ pstack ~postgres/core
core '/opt/postgres/core' of 19868: pg_upgrade --verbose --link --old-datadir=/opt/postgres/db/root/old --

As to the ownership, the bash script I am testing 9.1.4 and 9.2.0 with recursively chowns the directory that owns the old and the new PGDATA directory before running pg_upgrade.
