Re: pg_standby / WAL archive-restore through system restarts

Thanks, Guillaume.  Can anyone confirm his answer to the question below 
about restarting the backup postmaster? 

It seems counter-intuitive since the backup server is only waiting for 
new WAL files to restore, it would seem it could be killed and restarted 
at any time and it should just recover as it has been all along.  I can 
see if I end recovery mode this would be the case, but can't the 
recovery postmaster be killed without having it leave recovery mode?
