My fault: it seems I forgot to stop the backup in my previous attempt. I
tried this procedure and now the former master acts as a hot standby as
expected:

On the former master:

a) stop
b) cleanup pg_xlog
c) set archive_mode = off and hot_standby = on in postgresql.conf

On the former slave:

a) set archive_mode = on in postgresql.conf
b) psql -c "SELECT pg_start_backup('switchover base backup')"
c) rsync -av $PGDATA --delete --exclude server.crt --exclude server.key
--exclude recovery.* --exclude postmaster.pid --exclude pg_xlog
--exclude archive $SLAVE:$PGDATA
d) psql -c "SELECT pg_stop_backup()"

Finally I started the former master.
