assuming you have configured rsyncd on the server as:

[postgresql-data]
     uid = postgres
     path = /var/lib/postgresql/9.0/data
     comment = PostgreSQL 9.0 data dir
     exclude = postmaster.log pg_xlog/* postmaster.pid postgresql.conf

So you keep the old pg_xlog ... But, what about wal that the former master hasn't yet sent to the slave? I wonder if the former-master could apply them, becoming out-of-sync with the former-slave (that never recevied those wal).
