Hmm. That requires write access to $DATADIR, so that's not quite the same
thing as the trigger_file recovery.conf option.
Well, you also (elsewhere) requested that we must keep recovery.conf
in $DATADIR, so it needs to be writable.
That's a slightly different requirement. $DATADIR must be writable by
the process that restores the backup or puts the server into standby
mode, while trigger_file needs to be writable by the process that
triggers failover. Those are not necessarily the same thing. I'm
thinking of a heartbeat process that triggers failover by creating a
file on an NFS server or similar. Possibly the same location where the
WAL archive is located. $DATADIR would be stored elsewhere.
