I want it to failover in case the master become detached. I already had the value backend_flag0 = 'ALLOW_TO_FAILOVER' and backend_flag1 = 'ALLOW_TO_FAILOVER', but for some strange reason I saw twice that I have one server as master detached and the other server as slave attached. I cannot understand why the slave did not become master when the master became detached.

You can set backend_flag0 = 'ALLOW_TO_FAILOVER' or something like that to prevent a fail over. See the manual for more details.
