That's not a daemon process.

mythbackend --daemon

is, but

mythbackend

isn't.  And, when a non-daemon backend process is started in an 
interactive terminal, the master mythbackend will ask for permission to 
upgrade the database.  Had you started it with --daemon or -d, 
mythbackend would not have asked for permission to upgrade.

The master backend only defaults to upgrading (without prompting) when 
it's not started in an interactive shell.
